srp 81.5 mm 11.5-1 compression, 99 si head (stock), rc 310s , fuel pressure 45 psi, phearable chipped p28


question is when i get to about 6500 rpms it loses power and as soon as i let off the gas it stalls and dies. would this be because the fuel pressure is too high ?

ps asking question for a friend and its not yet tuned THANKS!!

 

I'm going to lean towards the chip. Try another ECU or program and see if the problem persists.

 

yea...its seems like its floodin out ill through my ecu in it tomorrow its a phearable ecu also but my set up is different then his....anyone else !!
