Default Afterfiring?

I installed Pacesetter LT's and TSP True Duals a week ago...

Yesterday we were hangin' out at the street and a couple friends that were driving after me told me that my car was throwing fire on the dumps.

I got into it and looks like my car is throwing flames while de-accelerating. There is no power loss that I can feel or anything, I have scanned the car (HPTuners) and so far there is no KR.

Huh? Would just be fuel that didn't burn getting hot on the bullets?

My car did this as well along with a few others. Is it popping backfire type noise on decel along with the flames. If so It is your airpump. Actually it is the check valves that are in the lines that go to each header/manifold. When the check valves go bad this happens. Trust me on this. There was a very good write up on this about 2 months ago. So just reove the air pump all together. Also if that doesn't work and the A/F is right on fully enable the DFCO with HPtuners. One of the two should cure the problem let me know.

I removed the AIR system so i guess that's not the problem...

I will get it on the dyno on Wednesday...

Just saw your sig.. Everyone is Running the TR55's.. I changed the plugs also for some TR55IX's. Maybe they are off?
