IX GSC S2 Cams, Stock Turbo
This car has a cat in it so the tailpipe AFR is not accurate. The 12.5 indicated is actually closer to an 11.8 at the testpipe. The drop from 3200 and down is I start the pull at 2400rpm and AMS chose 1700 so since they dont start at the same point it appears to be down power. In reality it isnt but since I didnt know AMS started that low I didnt get them overlayed the same.

^ Yes it is 92. Like Aaron stated tailpipe is differnt than at the testpipe on cars like this. I run into the same problem with street tuning a car. I have to know the correct afr as even the tailpipe on a testpipe car is still a bit leaner than it actually is.
I love the S2s. Prob the best cam on the market and def the best cam for a stock turbo setup looking for the best power and still retain stock like spool. Nice tune Aaron! OP I'm sure you are very happy with your car now.

Thanks for clarifying Aaron. Yeah, we can't really compare the lower end with 100% certainty. Besides, I'm never trying to accelerate below 3k anyways.
I updated the original post with the fuel used. 93 octane at AMS and 92 octane at English.
And yes, i am extremely happy with the tune! It's been way too long since I did any major work to it.

LICP
WGA 16psi spring
TBE 3" no cat
Intake
26psi
I made 354whp on a mustang dyno
I was wondering how much more power I can get get with the S2 cams with this setup. I can go with 28-30psi but not sure if that is safe.
I'm still debating if I should go with the S1's or S2's...my only concern would be daily driving with S2's... any feedback you can give on this goucho or anyone else with S2's. My plans are for a FP Green maybe FP Red later down the road.
