STS on built 4.8 01 Silverado ,forged 4.8 with 8.5-1 compression,ported stock heads,216 Cam,STS T67 Turbo with custom front mount intercooler,built A4,4.11 gears.
The pull was at 15lbs and was laughing at the boost/high timing.Also tuned with 89 octain gas
(thanks Matt 
)
This is just a baseline to get started.After some little stuff is fixed we'll be upping the boost///alot

Ya Don is the MAN!!!!! It had 89 in it because that is what I was running in it to break it in. I was in a eush to get it down there and forgot to fill it with 93. I cant wait to see what the thing makes with 93 octane and the few other tweeks.
Oh and the blow off valve is freakin loud It is under the hood right where the stock air box was. It get addicting.

I think we'll end up at 18-20lbs of boost when we are done 
Also the inlet temps were a joke.At 14lbs on the street the temp only went to 90 degree's going through 3 gears

glad to see it back on the road,
sounds really cool.
