    After LT tune.

    Ok, so I did my LTs and full exhaust and its all done but when I get on it it hiccups and backfires a bit. Is this only because its running rich and I need a tune or could it be something more?


    I used NGK TR-55s and MSD plug wires.

    Could be because its running a bit rich although double check your plug wires and plugs to ensure there not cracked and the wires are on good and tight.

    Yeah, I'll have to take a look over everything again, check the plugs and wires. I wanna know if other guys have had this issue and it ended up just being the tune.

    It could be the people who installed the parts

    I really dont think it would be the plugs and wires, but doesnt hurt to check them..As far as the tune, when i got my LT it didnt backfire or anything(i didnt have it tuned). The person who put them on recommended me to get better gaskets though cause the ones that came with my LT were real crappy..I would check that also..

    No, no leaks. I reused the stock gaskets, I already knew how shitty the gaskets they gave me with the LTs were.

    You got it Josh. Im gonna go mess with the plugs and wires and check things. If that doesnt fix it then its definitely the tune (which Im feeling is the real issue).

    I gotta look around for places to dyno tune.
