did this
JB4 vs Cobb comparison back early April in 93 degree weather at Cobb's facility.
Mods: ETS, DCI and 93 Octane
facility was impressive - nice and clean and everyone looked as if they were having a great time. friendly environment with smiling faces all around.
got strapped on the dyno and away we went.
1st set of pulls were JB4 Map 1 on 14psi: average of 311whp and 350wtq
2nd set of pulls were JB4 Map 0 stock boost: average of 251whp and 290wtq
3rd set of pulls were Cobb Stage 1 on 15.5psi: average of 326whp and 385wtq
sorry for the "picture" graphs but i didn't get the screen shots emailed to me - just the logs.
