So I just drove to get my car home to get it tuned and it was a 450km trip. I didn't go into boost the entire way but now at WOT it only hits 2psi and at 6600rpm it may just barely get to 4psi. I am running the 2.7" pulley with meth and I have been seeing around 5-6psi at WOT and 7psi at 6600rpm. Last summer I was running the 2.7" without meth and I was seeing somewhere between 5-6psi at WOT depending on the weather. I'm not sure what heppened on the way home. Could it possibly be the belt slipping? I am just ready to give up on the car, its just been one thing after another. I'm wondering if anyone may have an idea of what could be causing this. I did remove my gauge pod the other day to pull my boost line down a bit cause it was hanging out a but I figured even if there was a leak at the guage the meth which is set to come on at 4ish psi would start spraying regardless what the guage was saying it the light would only come on for the meth at 6500rpm (right about when to shift). Any help would be awsome cause I have to be at the dyno in the am and its a 1000km trip for me and this is my 4th one to try and get my car tuned and I'm ready to set the car on fire if it doesn't run.

By pass valve?


Belt?

Open the hood and take a look at the parts.

I would double check your vaccum lines and make sure the bolts holding the sc to the head have not started working loose.
