Great numbers !! Thanks for posting. They appear to be almost identical to those numbers posted last year on the Brenspeed site with the Steeda CAI and their 93 tune ..Thats the combo I run and enjoyed for almost a year now..Took my 2011 GT to dyno at Dirty Dirty Racing in Bedford Va. Pulled SAE 392 rwhp and 390 rwtq. Mods are Rousch axlebacks. Bama 93 performance tune, and Airaid cai. 3.73, M6, Brembos, dynojet would have been 403rwhp.
Lou did three pulls first was in 4th gear 375rwhp & 366 rwtq bad air fuel near 14. He called AM had them send another 93 race tune. That new tune pulled 390 rwhp & 378 rwtq a/f was spot on. Third pull was 93 performance tune and that one pulled 392.2 rwhp and 389.8 rwtq once again a/f was good. Temp was 88.3 F humidity 45%. Last two pulls was in 5th gear.
