Zippy, that's kinda like saying the Radix can go fast, or an ATI can't go fast. Just because a few people buy a kit but don't optimize it for darg racing doesn't mean the kits can't be made to go go fast. You of all people know that it's all about the combo and not 1 specific part.

I think the STS has proven itself over and over again with the GTOs, Angie@Thunder Racing's car, my truck, Allen's truck etc etc.

 

it ran a 14.4 at 98 on 5 psi...i never ran it on 8 psi at the track....he's got a 5.3 and i had the 6.0

 

I'm not saying that mine is fast but damn. Something is majorly wrong with your tune or setup. My best run to date was 14.268 @ 95.56 (1/4) in like 55 degree temps with plenty of wheelspin only being able to launch from about 900 RPM stallup. 60' was like 2.157 or thereabouts. I ran a 14.301 @ 95.29-60' of 2.201+/- in 88 degree temps just the friday before last. All mods in my sig except the latter I had cutouts. Plus now I have done weight reduction- about 150-175 pounds and running ET Streets 27". I am hoping to be in the high 13's come winter. This all on a N/A motor no spray or power adder and Yup, its a Crew Cab. Last weight was 4965 #'s with just a hair over a half tank of gas.

 

Something definately wrong. See mods and ET in sig below. When i ran this ET my truck even bumped the rev limiter on the 1 - 2 shift. I haven't been back to the track since I got the Custom Tune from Runnin With The Devil. I'm hoping to get into the low 14's to high 13's with a converter and a shot of nitrous.

 

how does the truck feel after the turbo install? Any way to see your KR, and or LT, ST values?
