Hey all, I've been having some issues with my 2008 Chevy Cobalt SS/TC. My mods are below and a description of the situation.
AEM Cold Air Intake
ZZP Intercooler Piping
ZZP Intercooler
ZZP Catted Down-pipe
ZZP ZFR 6758
The car is HP Tuned, and has been running strong up until recently. I have been self tuning for over a year now with a lot of success. I just figured it wise I seek some advice before I went poking around my car aimlessly.
The turbo was making 24psi and the MAP was registering 255 for the DAL. However now the turbo is barely managing 14psi, and the DAL is only registering 196.
My STFT's are also falling very negative, and the cars exhaust has a lot of pops to it now when it didn't before.
The car seems to be running perfectly fine in every other aspect. I checked underneath the car and the exhaust manifold is completely intact and crack free; as is the turbo. I checked the oil and it looks fine, and the car is not smoking at all either.
Any ideas or advice would be greatly appreciated.
