Don&#39;t it suck to get beat when running a 12.6?

Yeah, that guy went a better time than me through the 1/4. Coasting after the 1/8.

Sorry for the thread jack but is your 90mm TB opening all of the way? I have heard lots of guys have issues with that. I have a 03 SS with a radix 9psi, headers,TBTC,functional ram air hood. I have been considering this mod but is it worth it for the expense? BTW my best before the converter (and removing my cats) was a 13.51@101 and I weighed the truck right after the run 5750 with me in it. I have one of Allen&#39;s e-fan harnesses on the way for my 05 fans. Thanks

No the TB isn&#39;t opening all the way. Once you get to a point every little bit helps. I dropped from 12.70&#39;s to 12.60&#39;s-50&#39;s by doing the 90mm TB with no tuning so far. Might be a little more in it with some tuning. Know the air flow has changed. Truck feels better. Think I gained some torque with the mod.

that big truck launches great,
what rpm is the truck shiftint at?
what are the iat&#39;s at the end of the track?
how much timing is the engine taking?

great times,

Thanks Allen.
1-2 shift @ 6200, 2-3 @ 6000.
Haven&#39;t logged IATS in a while. With the meth before the 90mm TB IAT&#39;s 130-140 at end of the quarter with 70* ambient best I remember. Timing @ 22* WOT commanded. IAT temps drop it 2-3 degrees sometimes on the top end.
