Well i have been GIAC chipped for about 4 years now, and never got to asking about this, becuase i thought it was normal. but when you are flooring your car, say your in 5th or 6th gear. it feels as if the car pulls then stops then pulls then stops.. like the turbo grabs every other second. what could be the problem for this? a weak hose folding? what else might it be, or is it normal?

thanks

 

COuld just be boost spikes, get a Throttle Cut Defener and Manual Boost Conroller so u can regulate everything, She will probably run alot smoother for you.

 

Could it bea weak DV?

 

what years did the s4 have the throttle cuts? Is it only manual or auto as well?

Thanks
