so im at the muffler shop because I thought the install would be to much for me. For those wondering I have a magnaflow cat-back and em putting on fast intentions hfc with non foulers. My question is they didnt reset my ecu.Should I do this once I get home??

 

To my knowledge , it's not entirely necessary, but members do it anyways

 

so I wont do it then, see what happens. I wont lose hp right hope it dosen't sound like a stupid question and thanks for the quick response!

 

Nah you wont lose any power. Your car will adjust on it's own No problem.

 

I reset mine but that's mainly because of habit. The inifiniti tech told me that the ECU will "learn" the HFCs in a thousand miles or so. I figured wouldn't hurt to do the reset and it's pretty easy via the method outlined here:

you never know if resetting or not will be faster. so i just leave it alone.

 

yeah I decided to leave it alone and not reset it. It's been about two days so far and the car is slowly starting to feel a little bit more power. Only thing is I knew I was suppose to expect that infamous rasp noise in the 2k rpm range, but I also hear it at WOT above 4k. It sounds like a hissing noise is that normal?
