Sal,

I saw your post about plugs. But I still have some questions. I saw those new plugs at Cecil the other weekend. My truck has a #3 pulley (maybe soon to be a #5). I have the NGK #6's i am guessing the TR6's you talk about. They were fine at first but now I am getting spark knock in 3rd on 93 Octane. If I put a additive in the gas it goes away but it seems to run rich. I have tried a few of JL's program's. I am thinking its in my plugs now. I do not drive my truck daily but I do some pleasure riding at nights and weekends. What would you suggest?? Also would a 3lb pulley be to much if I wanted to add NOS ?

 

Richard: i would suggest that we re-burn your chip for the winter. the air is getting colder and leaning the trucks down a bit.. i also would suggest putting in the Denzo's IT20's or the ngk's # 7's i personaly have had great success with the denzo's i drive the truck everywhere when ever posssible and they have performed excellent on the street and @ the track..
