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.
