    Yeah, but I like my motor tune. With NA timing and a 125 shot I could probably be close to someone with a lower timing and a 150 without sacrificing my daily fun. I run around 28 degrees of timing.

    actually just put the NA tune back in yesterday....don't really notice much of a difference. Truck became a turd the day I put the TR6's gapped at .035 in though. TR5's gapped at .040 are going in tomorrow. If that doesn't help, i'm going to dig my 70k mile old delco platinums out of the trash and put them back in.
    blown transmissions are about as useful as 97% of the guys on this forum

    I noticed a rather large difference with only 3 degrees pulled. I can't remember what it felt like to not have TR6's, so I can't really comment on that. I put them in a week after I got the truck.

    yea i don't remeber what it feels like with tr55s i put tr6s on when i started spraying.....

    first i started on 50 then stepped to 100 on n/a tune with 28 degrees.
    got nitrous tune and started runnging a .056 pil on dry shot. knocked 1.3 seconds off time and A/F was at 13.5 ish (MAF wasn't compensating for fuel. i have LS3 injectors so i got plenty of fuel). so if i did a wet kit it should be alot better
    now i'm on a 31 degree timing n/a tune
