08 GSR Cobb stage 2
Ran cobb stage 2 with 91. 316 hp 304 tq
Mods: Nisei UICP
UR Cat back exhaust (with Mini muffer mid section)
AEM intake
Boost pill removed
85 degrees
Originally we put it on the dyno with the Cobb stage 1 aem and we were getting AFR dipping below 10!! In fact the car was hesitating in the upper rpms due to all the extra fuel. We then uploaded the stage 2 91 without the aem and found a perfect match. AFR were in the low 11's tappering down to high 10s in the upper rpms. With the boost pill removed, hitting 23.5 max, tapperind down from there......
For reference i added another graph of a perrin stage 1 with just a panel filter (perrin). 279 hp 307 tq was the best run. Same car, but before the exhaust.
