Problem with hesitation after installing side exhaust w/pro charger

I have a 2005 Ford Mustang GT with a Pro Charger... with a Cervini's side exhaust, diablo chip. Car seems to want to shut off when stoped. but only after I installed the new exhaust. Anyone have this problem or any ideas?

does the side exhaust eliminate the mid pipe?

You may have changed also either the pressure or AFR. It might be super lean. I would go get it dyno tuned.

and I don't suppose you have a wide band?

the car NEEDS more timing advance in the lower rpms to help burn the increased intake flow.

Okay I got another mustang... it's a v6 with 247,00 miles and bats living in the exhaust.

Running a procharger, same exhaust, no issues. I've been on the dyno 3 or 4 times since I installed the exhaust, but prior to those sessions the car ran fine.

Running headers / high flow cats on this car? If not your exhaust change would not fluctuate back pressure or A/F enough to cause stalling. The exhaust flows better, but it is not a free pass to the atmosphere. You still have mufflers, and if no headers, still have the cats and midpipe. Problem is lying elsewhere.

Check your maf sensor, be sure it's clean. Could be a coincidence that after the exhaust a routine maintenance item surfaced - especially with the blower on the car.
