I like the iats with the oem box much better, smoother maf too for running flex if not doing straight e. Just add drop in.

X force long tubes pbd tune I was having drivabiltiy issues with stock box and than added jlt pbd said the jlt helps.

I dont buy an aftermarker CAI having better driveability than a stock box. No way.

Hope you get it figured out . I have close to the same set up except it's a stick from PBD and haven't had any issues at all .

Car drives fine no issues no cel just don't want to shift into 4th gear in drag or sport mode.. I've tested some more and it dont do it in just drive so i don't think it's a transmission issue

I'd try putting it back to stock and see if the issue occurs on the factory setup and then go from there.
