milled head. need tune?
So not long ago i blew the HG in the SC running at Pocono Raceway. I took it apart and put it back together with ARP studs and cometic HG
, Head was milled down to .030, so I guess my compression is now in the range of 9.0-9.1-up from 8.5. Question is I am running the stock soarer ECU for my 1JZ, will it need a tune?
I fixed the exhaust leak and still seem to be running rich in boost, 10 flat AFR by the time im at 5psi and fuel cut at 11lbs; no codes... I have a Greddy EMU but rather find someone who tunes JZ engines around the boston area before letting anyone mess with my car. Any help is greatly appreciated fellas.

ok just fixed 2 more vacuum leaks via smoke machine and runs slightly better but still cuttin out in higher boost levels. Anyone have any ideas Im really gettin stumped on this. Mods are as follows: BC, front mount, BFI, custom y pipe and 3in exhaust. Anyone know of any tuners in the New England area? I'm no newb by no means but am a far cry away from being a tuner.
