I'm gonna post this here and the general tech area. I have the D1-SC and the motor is the stock cobra except for pro-m mass air meter, 42lb injectors, offroad exhuast, ati adjustable fmu and shorty headers. I have a mail order jms chip set-up for my current boost level. I'm running a 3.55" pulley and seeing 10lbs of boost. I'm going with a 3.35" pulley. I'm running a fairly safe tune. Do I need a new chip? Can I give it more fuel with the fmu and maybe retard the timing to avoid detonation? Thanks guys.
