hey guys i recently got my car tuned at maperformance but i couldn't get any good numbers because at the time i had a twin disk clutch which was completly demolished, and i also had a said "boost leak". turns out what i expected was right and the waste gate was SH** "forge wastegate" so i returned to a stock 8 waste gate, every thing was fine boost wise but the clutch was slipping soooo bad. I ordered my clutch had it put in the very next day. now the car is hitting "boost cut" at around 15 psi it jolts back and forth so i was thinking it was maxing out the stock wastegate. I replaced it with the rebuilt forge one and same thing i have a hallman pro series boost controller but its turned as far as it goes down. I'm confused about what this problem could be.

secondly im having idle issues i think it could be the iac or just a dirty throttle body how can i tell 100% thanks for the help

 

no one knows???

 

any one??

 

I always thought Forge was decent stuff. Well at least their bov/dv's

Have you gone back to MAP and asked about it? My wild uneducated guess would be a fuel cut.

 

thats what i thought too but with 1150's i dont know how it could prob just the tune. i line a good 8hrs away from map tho so it'll be awhile.

 

Another possibility would be sending him a PM. I don't know if he would have anything to do with the tune but he probably could get you in touch with someone that could help.

Even if it doesn't have anything to do with the tune, they may be able to point you in the right direction on a solution. I don't have any experience with map but I ask my tuner dumb questions on a regular basis.
