What is causing the banging and back firing on the camaro my bro and i are building. It doesnt start doing it until about 20 minutes into driving it. The camaro is a ss with a l92. It has the converter from 24 to 58. Thanks for the help. Is it just needing a tune or is it something else.

 

More info? Stock tune? Everything else stock? Stock plugs? Etc

 

I think it is on a stock tune. Not sure bc just got the car. It is a cammed l92. It has ngk plugs. It runs bad *** for the first 20min. then starts acting up so you have to let it cool down then its fine and once you drive it 20 more minutes it does it again. It also has a built 4l60e with a 4200 stall. It also has a ls3 intake and injectors. We want to figure out the issue before we start doing suspension.

 

Do you have the ability to post the tune?

 

No I cant sorry. Wish I had hptuners and knew how to tune.
