i drove the car out today, and stepped on it. i was boosting at max .8 bar... that's like 11 somthing psi. i think the chip (g-force) is causing it to boost that high. i didnt hit fuel cut either, that's weird... maybe the chip pushed back the boost limit.
i need someone who messed with timing to educate me... hm... who could that be.
thanks for the input too R&D.

Umm, where did you get the G-force chip from, no offence man but you don't seem to know what it does - contact the vendor and find out. Almost all aftermarket chips will remove fuel cut.

As for injector sizes, try this:

Those chips usually just advance the timming, make you run a little lean and eliminate rev limit... I don't like the idea.

i got the chip from a friend. he is using the same chip as mine. the chip was programmed for

1. intake
2. catback
3 hiflow cat.

i dont have the hi flow cat on, and i'm trying to make it run properly. i know it advances, but dont know how much, nor does my friend. the fuel cutoff point is pushed back to 11psi, and more fuel is being added. but u see... the dyno results are kinda weird. i might have to do another one and have the probe set at the downpipe.

so far, i only have intake, catback in my car.
