hey guys, i was driving a friend home and i opened it up in 2nd and 2nd only. it was accellerating strong at 8psi until about 5k when it started lagging and my boost rose to close to 12psi. Is this the so called boost creep? thanks -alex im still learning!

 

Sounds like it could be but what mods do you have done to the car

 

Boost creep = boost keeps increasing unless you let off the gas, and is caused by too small of a wastegate or a wastgate that is not fully opening for some reason.

Boost spike = boost increases initially, but then goes back down on its own, and is caused by a slow-actuating wastegate that takes too long to open up.

 

Definately need to know your mods to diagnose.

 

intake, RB turbo back exhaust, hks FCD, greddy boost manual controller. what happens is when im going full throttle my boost goes up but my cars acceleration slows down.

 

My car does the SAME thing IwannFC... I have very similar mods

 

yes

 

im thinking of poprting my wastegate, this will mostlikely cure this right? im also thinking of gettingf a bov, good way to cure this?

 

bov will do nothing. ONLY way to fix it is by porting the wastegate.

 

ok, now i noticed when i floor it, the car will boost but... the car will bog for about 500rpm and then accellerate normally for about 1000-2000rpm then bog again for another 500-1000 rpm. It does this in the upper revs. whats going on? -alex
