ls2 back firing question Ive been running my 05 ls2 m6 for 5 months now. its a all stock engine, had wait4me tune my pcm. running wise its fine.
but my question is: when driving and in any gear if i dont have my foot on the petal after 10 sec or so the engine pops through the exhaust loudly. i cant ride a gear down to slow down at all with out this happening.
Im running 2-1/2 exhaust and its all new with no leaks.
Also im not showing any codes w/light or with my scanner
new plugs wires, before and after no difference with the back fires
Any suggestion why its poping like it is? thanks
