We loved it!

Ami calls them "victims", and would hammer the Turq Monster just like that, given the chance!

I have a few more videos from that morning .. One of deccel in gear in which the sound is like gunfire in saving private Ryan I preferred the way it sounded on deccel before I removed the secondaries and had another chip done. I'm fairly certain I opted for the anti backfire Marc said he does and I'll have to talk with him about it but it definitely didn't snap crackle and pop before the recent changes. I'll try to get them uploaded today
Have Marc check his records. I had him reflash my chip after I installed headers, and the backfiring was OUT OF CONTROL! I contacted him and it turned out he had forgotten to enable the anti-backfire thing, which he took care of immediately. Could be the same issue on your car.

I sent him an email and my thoughts are exactly that. While it does sound cool.. for about 10 seconds... Im not much a fan of it. I know import crowds and turbo car people love it but that's because their cars sound like garbage and they need something cool.

when I did the headers, it was pure muscle on deccel. I do have a short clip of the popping Ill post in a few seconds...

The snap,crackle, pop comes from excess fuel being mixed w fresh air sucked into the exhaust due to the high vacuum created on decel. Ever see any ricer with a "fart can" that isn't completely BLAAAAACCCK from the soot of too rich a mixture?

My tips don't blacken much at all but from what I know and can google.. that's the cause as you mentioned. Theres a dramatic difference from the first video though.. none at all.. and just excessive in the re-tune after the top end porting/secondary elimination

Eliminating secondaries really doesn't have anything to do with it. On decel, the throttle is closed and secondary injectors are shut off. What happens is that with the changes, the fuel map needs to be modified. I have no secondaries, ported heads, more aggressive cams, headers blah blah blah. No gurgling.

If all you have is "popping" on decel, then it's probably not an issue with Marc forgetting to enable that feature. Mine was BACKFIRING!!!! I mean, pretty much every time I depressed the clutch pedal (even on slow 1-2 upshifts) the car sounded like it was going to explode. Popping on decel is just your low-restriction exhaust...my stock Stingray even does that when I have the valves open.
