Hi all,


I do not know very much about tuning so I figured I would ask here.



I bought a used 16 m6 SS last year. It came with headers, res and cat delete and already has some type of tune on it via an SCT tuner. I had it dyno'd last fall just to see where it was at and it hit 410 best pull.


I am adding CAI and MSD manifold this weekend.



My question is, should I use the tuner that came with the car to reset back to factory and have an entirely new tune done for the car, or is there a way to adjust the existing tune to accommodate for the new add-ons?



Thanks in advance for the help...

What version tuner, is it a BDX ? I have one, got it for free a while back and bought a custom tune from RDP (Dyno Steve). It's a couple hundred bucks but you get free lifetime tune updates as you add and change equipment. I'd recommend doing something like that so your tune is optimal. I can attest Dyno Steve is awesome, I put him through the wringer with a bunch of changes and he'd shoot me the updated tunes within hours of me sending him a datalog.


The HP tuners are pretty much the benchmark for our cars for hyper performance, transmission tuning, etc. The SCT setup is good enough for bolt-ons though...

The tuner that came with the car looks like its the bdx performance -- https://www.sctflash.com/products/sc...-tuners/sctbdx --

With what you're adding, you probably don't have to update the tune. I would do so but I'm an old man who worries about everything. Have fun with it!

Thank guys, I got in touch with Dyno Steve and we are all set -- appreciate the help

[Brudda*Termite]

Any time. Your car is a great color, second fastest one, haha

ditch the sct and get a dyno tune with HP Tuners.

[Jdfromga]

Just to update ---


Ended up getting the tune from dynosteve, then for shits and giggles drove down to a dyno shop and had it tweaked.


first pull put down 426hp @5500rpm and 437ft-lbs @4500rpm


after some very slight adjustments to air/fuel it put down 448hp @5400rpm and 457ft-lbs @4400rpm -- and this was on a 95deg day with stupid humidity


not bad from original dyno before adding the intake manifold and cai, which was 410hp

[Brudda*Termite]

Nice gain!

Did Steve make those adjustments while you were on the dyno? Nothing wrong with those numbers and a heckuva lot less than HP tuners with a custom tune.

[Jdfromga]

No Steve didn't make the adjustments. I'm sure he would have if I asked, but it was ok. I just had the the tuner ( Tony from Tuners, Inc, Orange Park, Fl ) make the tweaks while I was on the rollers. He had quite the line outside the garage that morning. I had to drive over 2 hours just to get to a dyno, and when I got there around 10am there were already about 7 people in front of me.

So he's a SCT dealer/tuner too then. Cool. My best friend from my Navy days lives in Savannah and has taught HPDE there for years at RRR. He knows a guy.....

[Jdfromga]

yeah, I gotta get this car on the track one of these days. Still need to do a few things ( change brake fluid for one! ) but I bet it'll be fun as hell. Only track time I've ever done so far was in my v6 camaro and that was a blast.



We definitely need a good dyno shop here. Only 1 dyno here at a bmw performance shop. I'm probably not going to do anything to the car soon will that require any tuning adjustments but send me the guy's info in case I need it. Never hurts to know a guy who knows a guy...

[Redlinez]

The guy in Savannah is Randy Carter. I don't know him or if he has a shop, I just know he tunes cars. I thought i heard he was building a shop there a few years back.
