CVF down pipes and Thermal R&D exhaust install with CEL

[brynbaily]

Ok guys. Finally the snow has melted here in the NE and I've gotten around to doing my down pipes and exhaust.
Everything seemed straightforward going together fit and finish wise. Now I'm throwing a CEL and idol is rough. Driving and beating on it everything is smooth.
My questions are:
- Am I missing something? Defoulers seemed to go in ok nothing is melted.
I just want to solve this before continuing to the intercooler, piping and tune .
- Should I continue on and when I install the ZFG tune will it correct itself?

A tune won’t correct a hardware issue and if this started after the install, you have a hardware issue. I would start by making sure the downpipe flange is actually sealed to the outlet on the turbo.
