ok i added an ASP 7 inch crank pulley like 2 weeks ago. for some more boost. i was seeing 5-6 psi with my out of the box SC trim with a boostmaster pipe. best run was 12.16@almost 113
when i added the pulley i also added 42 lb injectors and ditched the FMU, without a tune i KNEW it would run rich but it ran TOO RICH, it would drive fine but would get too rich under WOT and just hinder power output, it made 8-9 with the pulley but it didnt feel any faster, in fact it felt slower than what it did with 5-6 psi
well i plan to get tweecer this winter and tune the car for 42s and etc. but in the mean time i tore her down and put the 19s back on with the FMU. to make it run with a more ideal fuel air ratio that what it was. ( was blowing black smoke out the exhaust)
got the 19s and FMU back on and ran the car, MY GOODNESS what a difference. i finally got to feel the 9 psi for what it was. and it was good. car will PULL your head off. as long as its not spinning the tires. from a 2nd gear roll it will light the tires up with ease now. never did that before, even with all the suspension goodies i have.
bad thing is i had some bad driveability issues with the 19s it would idle rough and want to die. with the 42s it wouldnt die on a cold start ( probably the richness) but it drove alot better wouldnt sputter.
i think the 19s are just old. they are factory and never been cleaned or anything.
i dont want to run the FMU but i will for now until i can get another track trip in before the seaon ends for a good baseline. over the winter i plan to tune it and get it running better and solve my idle and drivability issues.
i still have to mess with the idle and stuff some to get it running a little better. i will try to get some vids up this weekend.
