vf34 problem

im very upset with my setup on my car. I went to the track last nite and ran a 13.8 with cobb stage 2.5. Before i had a dowpipe,upipe, exhaust, intake, and bov and ran a 13.5 at 102. ANd yesturday i only trapped at 100. IM not sure if cobb sucks with there tunes.. or i did the install wrong.. any ideas of what could be wrong? the car doesnt pull like it used 2. Was i suppose to get a bigger t fittin with the turbo updgrade? any help would help me

About a million things could be wrong. And, although I'm not a fan of Cobb systems, I think its a pretty cheap shot to blame them, when you installed the hardware yourself. I'd give 99 to 1 you screwed up your install. Maybe you need a more experienced eye to look over your work

my friend has this same setup, installed correctly. running the cobb setup, and the car totally hauls ***, compared to mine at stage 2. so my guess is, you didn't hook up something right

i have a right to be slamming on cobb. Go read there forums and look how many people have problems with there setup. And second of all i havent had full boost ever since i put one of there maps on my car. The install went great but i just cant figure out why im only hitting 12 psi, give me some ideas plz. I want to kno if its the actuall cobb or a mechanical problem.

if you have a FMIC or TMIC upgrade it can rob you of a few psi too (in addition to intake and bov)

ummm ... thats wierd that your only hitting 12 psi w/ the cobb stage 2.5 . when i 1st had the stage 2 my car would always hit target boost . not once did it ever fall short . and recently when i went to the stage 2.5 i'm always hitting target boost , around 16.5 -17 psi . did you change the restrictor pill . that might help , worth looking into . you should diffently look over your werk , there might be something that you could've over looked . when i did my vf-34 i had 3 of my buddies helping me . and we double & triple checked each others werk , just 2 be on the safe side .
