Ok little history. Truck has almost 59k miles on it had it tuned with 93 octane livernois performance tune. 4" cat back exhaust, and AEM dry filter. I have regapped plugs about 15k miles ago and set them to .30 . Before i regapped plugs it used to backfire alot under WOT with 93 perfv2 tune. Regapping fixed that about 96% of the time. I was wondering if i should just replace the plugs as it seems to be the only thing i can think of that is causing my clatter. Or should i go to like .29 and try that? Buddy of mine sais the 93 octane im gettin from gas stations around me probably arent really 93 octane. To prove this i put a bottle of octane boost at around half a tank. Problem solved. BUT i was wondering should i go ahead and put better/newer plugs in since its almost 60k miles? Im wondering if they are still set at .30 as i have heard people having them get outa whack.
It's amusing to see the difference in drivers here.
In abut 7000 mi, mine has never seen WOT
