N55 Dorch stage 2

[flippin30]

Installed dorch stage 2 today and followed instructions to the T. Test driving car and got on it full throttle to make sure nothing breaks, 2-4 pull and when i let off in 4th, it started backfiring like nobodies business. Car went into limp mode with no codes. Car struggles to start now. I suspect its dme related but i checked the connectors religiously before going out to drive. Help needed ASAP as my car is in someones driveway.

I'm assuming you checked the Dorch HPFP checkbox in MHD and re-flashed that after installation, right? Just double-checking since you didn't mention MHD.

same with BM3. If so check your lpfp. If it was weak already it might not be supplying enough for the new hpfp. Mine lpfp went bad at 70k miles.
