Previously I just had a Diablosport canned 87 octane tune with my SLP Loudmouth mufflers. On deceleration it would pop and backfire and crackle like crazy, sounded mean and nasty. I then added a C&L Racer CAI and a Bamachips 91 octane tune. While this picked up the performance of the car, the deceleration popping and backfiring is now gone. What happened to it and how can I get it back?

Haha, re-reading this now, could I have explained this in a more lame way? Lol.

what intake were you using before??

The airflow is cleaned up alot with the addition of the CAI and GOOD tune. It does effect the exhaust sound a great deal.

+1, a good tune, more efficent fuel burn.

If I'm remembering what I was taught a long time ago correctly... that popping and cracking is unburnt fuel which means a bad tune. While it sounds badass... it means you weren't getting all the performance you could have been. I have a C&L Racer, Borla Stingers and Doug's 93 Race tune and I occasionally get very faint pops and crackles.

That's what I was afraid the answer was going to be. I just had the factory intake previously. Oh well, I guess it's a good thing that it doesn't do this any more, however yes, it did sound badass.

My car pops on decel with just the stock programming and stock airbox. I even heard it pop so loud shifting into second at slow speed that it sounded like a gunshot. These cars are obviously set rich from the factory. All I've got so far is SLP Powerflow axleback.
