Jb4 issues after install.. please help!!

Just re-installed jb4 stage 3 on my n54 and still having issues. Any input guys will be greatly appreciated.

Ok, so after I installed it my CEL light came on, and then turned off after I restarted the car. I then checked for codes using the steering wheel, no codes were found.

I took the car out for a spin, it was barely pulling! Felt like the turbos didn't kick in and it felt like I was driving a '87 Hyundai.... then a Warning light (yellow small triangle) came on, and my cooling fan was working non-stop.

I parked the car in the garage, scanned for codes and here's what I got: 2f6c and 2e3..

I bought this jb4 from another forum member, is there a problem with it?

I'll appreciate all the input,
thanks

How come it was fine before jb4 was installed? First time I installed in last week, I had same symptoms, uninstalled jb4, switched it back to stock, and everything was fine...

Oh I see, probably due to the disconnected wire in the trunk for the flap..

I would definitely check your connections again, even if it means pulling out the JB4 and re-connecting all of the connectors. Don't forget the power connector as well.

If you're still having issues you might check www.n54tech.com and post there for advice.
