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.
