my boost proeblem is that when under WOT my car seems to stop and my RPM goes haywild moving back and forth at 6000 rpm......but when i do this at half open throttle my car the problem is still the same...as soon as my car car hits 0 psi this problem comes in and the car hesitates and like there is a missing sound from my engine...i hope u understand what i am trying to say......so please guys bare with me and your help will be greatly appreciated.....please help i am very confussed.........

check for popped off hoses...and check all of them...take off the y-pipe elbow for a better view. and be sure to check the vac lines with pills in them (the two going to your wastegate control and pre-spool control.) check to make sure your charge relief valve is working properly (should close during boost) and remove the intakes and check for shaft play.





I had similar problems...turned out my turbos were shot...but I hope thats not the case.



what are your mods...stock twins? sequential?

Do you think going non-seq will help in this case??
