Hey guys im new on these forums and i need some help...I have an 04 sti with some mods and just purchased a cobb ap but after i installed it im not hitting target boost...
mods are:
goodspeed fmic
cobb cranck pully
greddy evo 2 catback
cobb down pipe
greddy bov
cheep intake lol..
I really want to know if the ap works fine with a fmic and if not..Is there some map that i can download from the net that will work...the problems that i have are that boost is not getting to 15 to 16.5 psi like it youst to be before... it stay in 13.5on 4th and 5th gear and on lower gears it stays at 9.5 i dont know if i need a boost controll or what...the car runs to lean on high mph...note:im runing on stock turbo...if somebody can help me it will be good
thanks guys..

 

Hey all you have to do is call Cobb tuning and they will help you out,or you can go check out there web site and by the way lose the bov it will screw you in the long run.

 

I'd check for boost leaks but IMO
lose the BOV and get a protune for the mods ASAP
