Hi All!

I'm about 13 months into my S/C experience and have enjoyed the 100% reliability of the stock edelbrock setup.

HOWEVER, i'm starting to get that itch. It's a small itch. I'm wondering if anyone has seen gains by doing a custom tune on an otherwise stock edelbrock eforce kit. If so, what kind of gains did you see?

I'm wondering if I could gain HP with a pulley and tune, or even just a tune without compromising the reliability that this setup has had over the past year.

I dont want to do a cam, or headers, or fuel, etc.

So... is this not s thing? Not possible? Lots of views, 0 replies. :-/

Think of it as a nice suit. Your canned tune will be tuned for safe reliability of their supercharger unit. It will be “safe” across the board if you will. A good custom tune will optimize the setup for YOUR specific car. Like a custom fitted suit would fit your body better than the one at Macy’s. You will likely have some slight power gains, but I wouldn’t expect huge gains. It will be the most efficient it can be for your car though, and in my opinion worth it.

Changing the pulley on most setups will likely mean you’ll need to upgrade your fuel system to go with it, as pretty much all of these systems when tuned right will be damn close to maxing out your fuel system as it is. And with more boost comes more air, and more fuel to go with it.

Hope that helps.

I'm heading down this same path also. My local tuner has taken a peek at the canned Edelbrock software and he thinks it's the best canned tune out there. Not much room for improvement in his opinion.

I'm putting together some info on tweaking the E-force, including porting out the snout, moving the TMAP sensor, adding thermal isolation/plenum volume spacers between the manifold adapter and the rotor pack, and going to 3.25" pulley.

Work on this has stopped due to a broken wrist, but should be able to get back to it soon. Parts are all here. Mayish before I have some results.(?)

Awesome response, thank you. Certainly helps.

Got it! That's good to hear that the tune is good right from the factory. Looking forward to your results!

If you change pulley you’ll need to retune it anyways. Also, did your tuner just look at the canned tune file and say it looked good or did he actually put your car on a dyno and/or do logs on your car and then say it looked good? If it wasn’t the latter then it would be pure speculation with nothing to base it off of really. Sorry not trying to be an ass, I’m just curious.

The tuner's comments came from an initial, baseline dyno run when the E-Force was first installed about 18 months ago. He too was curious as to what the tune looked like and took a little extra time to investigate, including looking at some of the tables. It surprised him with the quality of the tune. This is coming from a tune shop that offers their upgrades to C7s and Camaros as a dealer installed package and are well known regionally for their work on C7s.

The tuner and I have been talking about what I have planned and we both want to get it in for a full tune, including VE tables. Frankly, I'm not expecting to see dramatic changes in power with what I'm working on, but I hope to be surprised.

Interesting. I'd expect the tune to be at least a bit rich.

Regardless you can always make it worth your time by picking up a meth kit. Alky Control is popular, but there are cheaper options out there that work well. Like Devil's Own.

That way you are guaranteed to have some extra timing on the table.

Good thought, but I'm not really interested in a meth setup. Had one on my Audi TT and it was a PITA. Leaks and seals failures were problematic over the long run. Finally removed it and took a small hit on power. The reason I've fabricated the thermal isolation/plenum spacers, as well as moving the TMAP to a different location, is to improve overall timing and timing recovery. My setup is a DD, so I'm not interested in maximizing everything. 600 to 625 rwhp is my goal.

Having said this, I have cut some 3/4" spacers with the thought of maybe installing either NOX and/or water-meth injectors into the spacers. But this is a future project that may or may not happen.

As for the AFRs, take a look at the graphs at the bottom of the first page for the Edelbrock canned tune AFRs.

Edelbrock's tune is a little lean on tip-in on the dyno, and then goes fat as you would expect. I was always happy with the performance of mine until it came to warmer weather and 130+ IAT's which resulted in pulled timing. Killer chiller fixed that, and is a great mod if your car is a DD like mine. Makes it drive like it's 50 degrees out all the time, except you have the traction of 90 degree weather. I doubt you'd see more than about 10 whp in gains from just a custom tune with no other changes over their tune.

[Atomic Ed]

Good to hear from you Dave!

I would, maybe will, go with the Killer Chiller approach before I would do meth injection. Particularly for a DD.

This is what JRE specializes in, taking base supercharger packages to the next level.

We can provide the parts, the tuning solution/equipment if needed and the custom tuning to bring it all together.

Feel free to give us a call.

What scares me with your killer chiller thing is the effectiveness of the A/C system going down. I dont think i want to bother with that!

Hi Ted, we exchanged PMs about 6 months ago. I wasn't able to get you the log files you needed to figure out if there was any room. :(
