Hey guys having a really weird issue with the cobalt so here’s the back ground. Car is a 2009 ss/tc aftermarket ldk block and and turbo. K&n intake, gm stage 1 maps full exhaust, intercooler etc.

up on stsrt up the car runs fine, tuned on HP tuner to about 22psi and made 333 whp. However after about 5 mins of driving the car goes into a limp type mode. It only allows for 4 psi of boost and throws code p0101. I have installed a new maf and the maps are brand new as well. If I shut the car off and restart the car goes back to being normal for a few minutes then goes limp mode again.

Another issue (unknown if related) when the car is boosting correctly and I get on it for a full gear pull the clutch seems to be way different if not dangerous or inactive. I almost have to pull the pedal up and it takes several minutes to get the correct clutch feel back.

Boost leak. Is it stock intercooler or aftermarket?

Do an actual boost leak test, don't just check.

Other potential is wiring to the maf, but is put my money on a boost leak, so build a boost leak tester and find the leak.
