I hope I didn’t scare you off, it is an acceptable risk imo and I run it on my car which is raced many, many times each year. You are probably not going to see any appreciable differences with the P&B tune from EC or from Tork unless you’re running a race team with your car.

I used VP Racing HP100 race gas to bring up the octane level to 94.5-95 octane. HP100 is oxygenated with 10% ethanol so that evens the playing ground as compared with my EC Phase2 dyno results on 94 octane with 10% fuel (AKI is about 94.8).
On another note, my friend's Abarth with a super spring exhaust is around 195whp on the same dyno, whereas I have an ATP 200cell catted downpipe. I'm curious to know whether there really is that much restriction in the stocker exhaust.
I put a NueF single exit rear on the 500T... It's still quiet as fuck to my ears compared to MAD FIAT. I can't believe the stock exhaust is that quiet! Either that or my hearing is going ....texanbrit wrote: ↑Wed Dec 19, 2018 10:32 amThanksdoverosx wrote: ↑Wed Dec 19, 2018 6:47 am I dynoed the Tork tune with 91 octane fuel without ethanol and got (186, 185, 182whp) at which point heat soak was really affecting the car.

It's been so long since I've run the stock exhaust. I assume the stock cat is a bit of a bottle neck, and the stock axle-back is not well bent so the pipe actually goes down to 1.8". It's a sound restriction if nothing else
I have the stock exhaust from the cat-back. There is a downpipe and that obviously makes a difference in flow (+7whp/+7wtq). I'll be on the dyno with Stage 2 once John finishes filling in some more eagerness in the lower revs. Up top, stage 2 is pulling so smoothly and quickly now that it doesn't even feel as fast as it actually is. It isn't surging or peaky, it just goes all the way toward fuel cut.texanbrit wrote: ↑Wed Dec 19, 2018 10:32 amThanksdoverosx wrote: ↑Wed Dec 19, 2018 6:47 am I dynoed the Tork tune with 91 octane fuel without ethanol and got (186, 185, 182whp) at which point heat soak was really affecting the car.
