I just placed an order for the P1X Procharger, with Stage II intercooler, for my '16 SS. I started reading through the installation instructions and noticed that they recommend using an NGK 6510 spark plug (which are a heat range 7, and 2 steps colder, from what I can tell) gapped at 0.35". This has me a little concerned, because I currently have a nitrious system installed (I'll be removing it when I install the Procharger), so I've been running NGK 6509's (heat range 6, 1 step colder) and I have a fairly significant problem with misfiring (yes, I do get a code), and the car bucking, when it's cold outside (anything less than about 50 F). I live in central Illinois, so it does get cold here, and while I rarely drive the car in the winter, and never if there is snow and ice on the ground, the late fall and early spring mornings are still relatively cold.

I've read through all the posts I can find on this forum, regarding plugs with the Procharger, and while I've seen several people mention a rough idle during a cold start, they also all seemed to mention that it went away rather quickly. In my case, with the 6509's, it could take 5-10 minutes, of warming up the car and/or driving around town, for the car to warm up enough for the misfire to go away, and I would expect this to be worse with 6510's.

So, are there any recommendations on what I should use (6509 or 6510)? If I continue to use the 6509's with the Procharger, am I going to continue to have the same misfire issue, or will the supercharger help eliminate that?

Also, this year, I switched back to factory plugs when it started getting cold outside. so since I've yanked on the wires a handful of times now, and will need to do it again when I put in the supercharger, I'm considering replacing the wires while I'm at. Any suggestions for what wires I should use?

You should really read this article before you get rid of your Nitrous IMO keep it. Do you have a standalone fuel system for your Nitrous?

https://www.lsxmag.com/tech-stories/...boosted-engine

Your tuner should no which plug you get should based on your engines HP, type of fuel your using pump, E85, or race gas. Compression will also effect choice of plug with ignition system as well.

Here’s a good read on plug choice but your tuner should know and if he doesn’t know get a new tuner.

I don't have a stand-alone fuel system for the nitrous kit. I was using the nitrous system (which had all the bells and whistles, plus a timing controller), and I'll be using the supercharger, on an otherwise unmodified engine, so I would be very concerned about exceeding some sort of engine power limit, if I were to use both the nitrous and supercharger.

I also don't really have a "tuner". I was planning to use the stock Procharger tune initiallly, but likely will find some place to tune it, in fairly short order.

Using a generic procharger tune is mistake, the car will run like crap and be extremely conservative. Find a tuner who does procharger builds and ask the tuner which plugs for your set up. The tuner will be the most important part of your goal/build.

I have run the same LTR7ix plugs on my car for going on 4 seasons with no issues. The only thing I have noticed is a little more cold start misses but it doesn't trigger a code. I think it has more to do with being on Ethanol than the plugs. A friend of mine runs a 7 heat range plug in his H/C LS 4th gen with Nitrous on E85. Also no issues. I wouldn't run a 6 heat range on a Nitrous car unless it's a 100 shot or less. A mild boost setup can get away with a 6 heat range...Jenetty tunes them a little more conservative for those that daily drive their car. If it's a weekend toy and will see frequent WOT pulls put a 7 in it.

My guess is you have something else going on if it's triggering a misfire code. And I also agree with others that the Procharger canned tune is shit.

I'm in Missouri, so similar weather. I use these wires:

Also I am using the Procharger recommended NGK 6510 plugs and running approx 40-50% eth, and no cold start issues down to 40 degrees. Haven't tried starting in anything colder.

Only use the Procharger tune if you have no other way of getting it to a tuner. It's downright abusive to your engine. Def don't do WOT with it as you wont get proper power enrichment. Okay to use it for "normal" driving IMO.

I think getting a base tune from a remote tuner is much preferable, and cheaper. I think folks like Rick Clarke charge a couple hundred for a tune that should be pretty darn good, and maybe even cheaper than what Procharger would charge.

If you want the dyno numbers, then maybe take it somewhere to tweak final timing and MAF/Speed Density/etc after applying one of those remote tunes.

For mild boost levels 7 or lower I am OK with LTR6IX.

I found 7s would foul in cold weather years ago.

Stock plug wires are fragile and if you had them on an off a few times I would bet dollars to donuts that is where your misfire issues are coming from.

I recommend MSD direct fit wires, we stock them if that helps you.

I offer Remote tuning services and have retuned many Procharger cars with very impressive improvements.

Other things you will need to support your procharger that are not included

JMS fuel system voltage booster

Hptuners credit to tune the fuel system control module.

3 bar map sensor

DSX baro break out harness.

I also don't agree with closing the gap on the plugs below 0.040 for best performance.

If it misfires there is something else wrong.

If there is anything I can do to help don't hesitate to contact me.

In my opinion, your current nitrous system is a better choice for the SS than installing a supercharger with just the canned tune. Seriously, have seen plenty of disappointing results happen doing that. One example, check out cjperformance's thread on his P1X with the canned tune, it went just 117 on the dragstrip, hmmm. Another example, I have seen a canned Magnuson setup on the dragstrip, and it was very unimpressive as well. Furthermore, my own Paxton with just the base tune was honestly slow as shit. THEN after some work on the tune, mine ran 10s in summer weather with stock motor/stock converter. Decent custom tuning needed, or just don't bother with the blower, in my opinion.

I understand needing the credits (kinda), but what do the voltage booster, map sensor, and break out harness do for me? This car isn't a daily driver, but I do drive it several days a week when the weather is good, and occassionally take it on short road trips, so I'm not looking for a super aggresive tune...I need something that's still fairly reliable and driveable.

Credits allow the ability to adjust fuel pump pressure for the in tank pump.

JMS fuel system voltage booster stabilizes voltage to pump control module, and raises voltage during high fuel demand so you don't drain the pump and lose fuel pressure, lean out your engine and break a piston.

Map sensor that comes in the LT1 is only Vacum to atmosphere sensor will not read maifold pressure in boost.
The 3 bar sensor allows the computer to read boost, which effect torque calculations, fueling, timing, throttle control, transmission shifting and a host of others.

Procharger system disable the Barometric pressure sensor that is located in the MAF, it was never designed to see boost so it sets codes and freaks out the computer setting codes and reduced power mode.

Disabling the Baro sensor also disable your computer ability to compensate for Altitude change or Barometric pressure changes.

So the Baro Break out adds a Baro sensor back in to the system which regains everything lost.

If you want your car to run at peak performance, operate properly, get decent fuel economy, transmission to shift properly torque management to work right, Throttle to feel right, Traction control to work right car to run right at different altitudes and weather changes.

You can follow my recommendations and do this right.

People make the comment I do or don't want an aggressive tune.

In my world there is no such thing, there is only right and wrong!

It's a bit disheartening to spend that kind of money on a supercharger kit, only to find out that I need to spend more, but I certainly want to do it right. Perhaps I should have asked these questions before I pulled the trigger, but I probably would have still made the same decision.

In all honesty, I'll do some price comparisons, but can you confirm that I'm looking at the right stuff? Plus, maybe the links will help the next person.

Understand, the supercharger companies are all in competition for your dollars, so the lower price wins in most cases, especially if you didn't read the fine print or research.

We removed the note about a 3 bar sensor option on the Baro Break out, you would never need a 3 bar for the baro break out.

Don't let price drive your decision that is how you got in to this situation.

Customer service sellers experience, should be priority over dollars.

The same reason you go to restaurants.

Any further questions don't hesitate to ask.
