I did the check the code for the check engine light, it told me that it was the oxygen sensor. I looked at every hose and I found out one of the vac hoses was disconnected. I put it back in place, now the check engine light is gone but the boot gauge won't move from 2PSI. I already bought a performance pre-MAF boost hose because most of the people told that the stock one won't hold more that 17PSI and my car is at over 18-19 right now. I did take it for a Pro tune about two weeks ago, but the bad thing about is the shop location is two hours away from where I live. When I did my last tune, they had everything ready for the inter-cooler swap in the COBB AP. So I'm really hoping the MAF hose fix the problem. The car has injen intake, perrin DP, SPT exhausts, COBB AP stage 2, running 303 HP with 356 LBS of torque, so the configuration is fine is just the intercooler swap that messed everything up. Thanks for you guys input.
