How much of the gain is due to the headers and how much to the reprogramming of the ECU?
We are seeing 41-42whp on the headers and 15-16whp and 10lb ft tq on STG 1 flash but the STG 2 sounds like 20-25whp and 15+ lb ft tq
we have not had a chance to make it back to the dyno to finalize the tune. Money2536 had the 2nd revision tune and should be comparing on the dyno soon.
I traded my Akrapovic for a set of DMS race headers. Should be installed anytime in the next 2-10 days.
I know i will miss the Akrapovic sound but more power always dominates
I drove the GT3 with no cats, headers and oem center mufflers.
Sounds great with this much power added, weight reduction, workmanship and price point this setup is a no brainer.
Another additional big benefit that you possibly could get with a tune is that the flaps can be permanent open or closed with the exhaust button.
Of course you could just unplug it and drive it open all the time but the car is such a nice quiet DD that I'd keep the flaps active for when I'm using blue tooth for phone calls..
Yes, it's actually 8750 in 2nd gear but who's splitting hairs lol!
The engine in SportAuto is mostly restricted to 8550-8675
I don't like Sport + it constantly feels like raping the engine and gearbox for no reason. Some get goosebumps, I cringe.. And that's with lower RS RPM's...
