Ok, i have been having some issues with my gm stage 1 lnf cobalt. Long story short, my car doesnt pull as hard as it used to and it seems to be lacking power in all gears. What i mean by this is that it seems to build boost but once it hits max boost it doesnt pull as hard. My mods are gms1, k&n sri(I had this problem way before i put the intake on), dejon hotside pipes, synapse intercooler, Clearimage 3" catted dp and 3" catback. I have had it to the dealer many times and they just keep replacing parts but they dont know whats wrong. So far they have replaced lower gms1 map sensor, vacuum tank, bpv solenoid and i have a new bpv rebuild kit on the way. Im wondering if you guys can look at the log and maybe point me in the right direction. All my sensors look like they are performing up to specs. I do hear what seems to be a high pitch squeel when i hit about 15psi and in the higher rpms, but i only hear it with the intake on. When i put the stock intake on, I cant hear it. I have double checked and the intake is on tight and the noise seems to be coming from inside the turbo.
Thanks in advance
