I apologize for the cross post, I was unsure how to delete my original message!
Today while doing a little spirited driving I got EPC light and CEL. Carista showed P0299 code. Poked around a bit and was hoping for a little more insight. I found the light would come on around 6k RPM. Never went into limp mode and it still seems to pull pretty hard.
I installed a CTS CAI in Friday. I have Unitronic stage 1+ and CTS muffler delete. Thoughts on where to start to troubleshoot?
I found the hose from the CTS turbo delete connecting to the turbot outlet pipe was loose and leaking... tightened this up and went for a quick spin at lunch and did not get the EPC light!!! Phheewww, at least this time around!
