2011 Corvette Grand Sport / PFADT Long Tube Headers
This is the initial start up of my 2011 Grand Sport after installing PFADT long tube Tri-y Headers with CAT-LESS mid pipe and factory Bi-mode mufflers with open ...
Yes they are low because of Pfadt 1-3/4 headers. I swapped them out for
American racing 1-7/8 and made 600rwhp with the same mods. Pump gas, local
tuner see other vid

Who tuned it and on what octane those numbers are LOW!

Just a quick dyno pull....I'm putting together a video with the results as soon as the shop sends them to me....but just wait till you see how it did :)
Love how it improved the sound from the jerry cans. Can't wait to hear how
they sound through my Corsas! Lookin' forward to the torque sheet from that
chassis dyno...I haven't peeked at the LSA results yet - don't want to skew
my hopes for my LS3.
