Just wondering. I6 options are: westers, but i would hate to have a tune i cant play around with. Then theres BS3 and thats bucoo buckos. Supposedly Hptuners is working on it as well. Just wanna keep my options open. Possibly MS would work, but havnt herad of anyone trying it. Any thoughts...

I haven't heard anything yet and I've been desperately looking for something that'll do good for the $. Everytime some company brings up that they're working on a tune for the I-5 it's always "6 months out"... I've heard that for over a year now...

I am lookin for a tune for a 4.2 I6 if any one finds one let me know

There's westers, and jet crap. Hp tuners said soon, but who knows how long that will be. I see you ran 16's stock. Don't worry it only gets faster, i ran a 15.7 with just intake and exhaust.

yeah the 16's were in about 90 deg weather also, i think i could break 15.9xxx with out intake and exhaust. hopefully, maybe 15.5xxx with intake and exahust I just need cold weather, and lighten up the truck a bit more. but i have to waite till spring now. it sucks,
