yeah my boost wont build above 14-15 psi and theres no power to the car whatsoever. the boost will spike to around 14-15 and fall to around 12 and stay there. the car has no pull. its like its bogging. anybody got a input

 

Have you checked for any boost leaks or has one of your intercooler pipes maybe popped off?

 

Boost leak test. With the bunch of mods that you have listed I guess it should be easy for you to perform said test. Have you changed anything in the wastegate line or something?

 

i dont have that t3/t4 kit on yet. im still running my 20g9. boost is set for 23. when i floor it, it misses around 5-6k. havent changed any wastegate lines. ill do a boost leak test and check it out. if thats not the case what else could it be??

 

Any CEL. Hard to tell without more info

 

yes i do have a cel. not sure what the code is. im gonna stop by my buddy's house tomorrow. hes got a scan tool. i had a code about 2 weeks ago. i think it was p0401 which is insufficient egr flow. it also had a code that there was a misfire on cylinder four but that was just a loose connection on the injector plug. i took care of that and reset the ecu and didnt have any cel til today. i dont know if maybe the p0401 came back up or not. im gonna check it out tomorrow. i dont think that would have any affect on my boost though would it???

 

i tried to get the stuff together for the boost leak test today but i couldnt get hold of the rubber coupling. i got the pvc cap and the valve stem. im gonna give it another shot 2moro. still got a cel on. im gonna take off the egr valve and clean it even tho i dont think it has anything to do with my problem.

 

definitely sounds like a boost leak...

 

^ +1 ...
