Problem:
Loud backfiring/popping from tailpipes upon decelaration, zero% TPS at 2500 to 1000 RPM's (1st - 3rd gear mostly).
After entering decelaration, popping and then loud backfiring occurs after 4-5 seconds then seems like fuel is cut, stays off until I add more fuel (EI;tapping gas pedal).
CAR: 2008 C6 Corvette base model, 29K miles, M6, Kooks 1-3/4" headers, catted mid pipes and x-pipe, Corsa Sport mufflers (2-1/2" inlet), K&N air filter.
Exhaust installed at E.S.P. in Sterling, MA.
Stock tune.
The backfiring started after installing new exhaust.
I own my own HP Tuners S/W and license.. I am familiar with HP Tuner S/W.
Also familiar with DFCO. Probably need to change some parameters in > Engine > fuel cutoff tab .
1)What is the solution to eliminating the terrible backfiring??
2)Can someone help with a solution?
Thank you,
Very Sad!
