OK just changed my plugs. went to TR55 thats what the guy at the store said to go with.. (he has a low 11's TA on spray 12.00 street tires all motor).. Gapped the plugs at .038. It didnt fall on its *** to bad, but it still did it. it will pull hard then when i let off its starts to spudder!!!!!!! I tried going from 1st to 2nd spraying hard. towards the top of second it started to fade then when i let off its started sputtering bad again[:@][&:]???? to much fuel?? maybe go a smaller jet or something?? AHHHHHHHHHHHHHHH to pissed to go check my plugs right now let me know some more ideas please..

is your timing at stock and also what type of kit do you have?

Yes timing is stock. I guess it would be considered a NOS kit. NOS power shot soleniods and NOS fogger.

You should retard the timing a bit

its kinda hard to do on a 99 and newer. Anybody know how without getting a timing controler?

TR55s are stock heat range. You need to install NGK TR6 plugs. They are 1 heat range colder than stock.

Make sure you are on stock tune, make sure your intake isnt throwing off the a/f ratio from a bend or air leaks, and make sure you have the right jets installed. Check all the wiring twice. The better the wiring, the better it will work.
