Went in with 162 with 15degree timing and stock fuel pressure. Came out with 165 with 17 degree timing and about ~46 psi. But i im also wondering why the cams are not holding power till atleast 7000rpm.

nice power! looks a lil lean but that could be a lil from the cat. There is a restriction up top somewhere, hmmmm

Very nice #'s! I'd be a happy man if I could hit those #'s someday.

Not much gain with cams.. maybe there were some cams like S3.

Btw. i want to get 160-170whp (190-200ps) with JDM DE, S4, HC CAI, 4-1 header, 2.5" exhaust and Calum ECU.

it is on the lean side. i turned the fpr to ~48 and it lost power. the tuner guy said that the top end is good but the mid range needs some working on. maybe next year ill have a calum rt and some 4-1 headers.

nice my numbers with S4s were 167whp, i have similar mods and no flywheel and a gutted cat

does your power fall off at ~6700rpm?

Thermoblock spacers shift your curve to the left. If you peak out at 6700 that's pretty good imo.

You added header and cams at same time? Your gain is only 3whp at 15° timing and 6whp at 17°. What header you were running before?

i have to find my dyno sheet im sure it was around that
