Reply With QuoteAdjust the wastegate to boost less....20 psi on stock turbo is no good and u will never hold that much to redline. Anything over 15psi you are going to spike and drop to around 15...
No heavy mods just CAI, Exhaust, a blow off valve and Diablosport Predator on the perfect 93 tune. I dont know whats causing it to spike. A week ago it was peaking/holding 17psi. Any suggestions?? im kinda new to the SRT-4s.

what im lookin to find out is why its spiking. The wastegate was never adjusted.Originally Posted by DSurick
Its spiking BC the Turbo can't hold that much boost to red line. Its normal for this to occur.
