So im driving down a back country road couple hours ago and i decided to put my foot into it. got my normal 17.5 psi in 3rd gear then shifted into 4th and kept the pedal to the floor but i could feel a rather large reduction in power and from then on out i cant get over 7psi regardless of gear or amount of throttle. any ideas would be greatly appreciated. Mods are in my sig.

thank you in advance.

btw no cel's or anything at all on the dash...

anyone have any ideas at all? should i be driving the car?

 

Belt slip. Or is your Boost bypass valve came loose and moved is can effect total boost. IDK if it will that significantly though.

DO you have any squeeling?

 

no squelling no noises at all. the belt and pulley only have like 3000 miles it shouldnt be slipping... anyone else???

 

You can only get 7psi of boost no matter what gear. It sounds like it should have something to do with the boost bypass valve sticking open or maybe a vacuum leak. Not 100% sure, but if you need me to come down and scan the car and or check it out let me know

 

thats whats weird. it isnt throwing any codes or anything. no noises. i briefly checked for leaks but could hear or see nothing... hmmmmmm
