I installed a 5" turbo back straight pipe, CAI, EGR/Cooler delete and an edge juice race tuner. After installing everything I started the engine and I keep getting codes on the programmer and a check engine light that wont go out. The codes are all in reference to the egr and O2 sensor. When i took of the exhaust I unplugged everything that was attached to the exhaust and zip tied it under the truck. I have tried to clear the codes but nothing seems to work. Any ideas???????
