Latest update: we just had @cognizantphotos 2016 PP GT in the shop for some dyno tuning, he brought his car to us with only long tube headers and exhaust (untuned) and wanted a dyno tune for his headers and yet to be installed restrictorless Steeda CAI.
With long tubes and exhaust, Joe's car put down 405 rwhp and 359 ft./lbs. tq. - again this was with no tune.
We popped in our Steeda CAI without the restrictor and started working on a tune to also accommodate Joe's long tubes. Our tuning mindset strives for great drivability with maximum (safe) power.
We're definitely pleased with the final results: 442 rwhp and 399 ft./lbs. tq.! Testing was done in a controlled environment with IAT 10 degrees above ambient and cylinder head temps right at 200 degrees for all pulls.
I'm including a couple additional dyno sheets to show both low RPM gains and high RPM gains. At 3,000 RPM you can see a 61 ft./lb. tq. increase and right at 6,700 RPM you can see a 47 rwhp and 36 ft./lbs. tq. increase!
These are stout numbers and we're happy with the gains, we know Joe will be as well - especially with how amazing the drivability is.
Videos to come shortly. PS - Kooks long tubes with Borla exhaust sounds amazing, especially at WOT.
