gutted DP now boost creep

Post by The Scooby »

gutted my downpipe the other day trying to eleminate my problem, now it still runs like junk, and now im getting boost creep like crazy, had my MBC set at 8psi, gutted it and then on the way home i noticed i kept hitting fuel cut, so i cranked the boost all the way down and im still getting 11psi.

what can i do to eleminate the boost creep?

so what exactally happends, does the increaced flow hold open the wastegate slightly? or does the increaced flow just allow the turbo to spool to a higher rpm?

you've got a possible line leak with your MBC or with a line feeding your MBC, or with a line feeding the wastegate


That can lend itself to boost creep, also clogged cats/exhaust restrictions can lend themselves to boost creep
