No Boost. Need Help! Sequential guys where are you.
 

Okay well yesterday i went and got the car tuned. Was getting boost perfectly fine until after the tuner was done. I was driving him back home and then it started bugging out. I would get no boost in 2nd gear. So then i thought thats was weird. Then all of a sudden i start hearing this weird sucking noise actually like the turbo was sucking through a straw. So then it hit me, i dont think my secondary turbo is kicking in maybe the butterfly isnt opening? But it's weird because it was before. She was boosting fine while it was getting tuned. But now she just makes that weird sucking noise as if sucking through a straw. Now today i drove her around and got boost in first gear and then nothing after that. Just that weird sucking noise and no boost. But if i mash on the gas while driving, and do it repeatedly she will give boost for a few seconds and then nothing again. Could this be a soleniod bugging out? Im about to just replace all the check valves with the ones Dale sells and try and get some new solenoids? Anyone have the major 3 lying around that i need? CCV, CRV and turbo control? I removed the rats nest and im running the simplified sequential system. I also replaced all the vaccum lines with new ones. Any suggestions?

Check Valves and Vacuum / Pressure Tanks.

If it's a sucking sound, I would check the vacuum tank first.

cool, i just ordered the check valves from dave.

but see i get boost some time so maybe a bad check valve?

www.autosportracetech.com check it out and get some facts

who "tuned" it?

sucking noise is often a massive boost leak from one of the couplers along the intake tract.

A very good tuner in Brooklyn. And no its not the intakes. I just put them on the night before and we checked EVERYTHING before we tuned it. Everything was hooked up correctly. No boost leak or vaccum leak anywhere!

hmm i think its that butterfly in the pipe that goes to the secondary turbo. I honestly think its stuck. That was my very very first guess when it started doing it and i think thats the culprit. Thats a dam good web site. Im gonna clean it with some good ole wd40 and a tooth brush tomorrow.
