Custom tune vs mail order dyno numbers
Just wanted to share my experience with a custom dyno tune vs. American Muscle and Brenspeed mail order tunes.
Brenspeed tune (dyno 11/10/2010): 359rwhp and 345lbs-tq. (calculated dense altitude of 1768)
American Muscle (BAMA) tune (dyno 03/12/2011): 371rwhp and 342lbs-tq. (calculated dense altitude of 1659)
Custom dyno tune (dyno 03/12/2011): 387rwhp and 355 lbs-tq. (calculated dense altitude of 1659)
Attached you'll find the images from the dyno runs (Brenspeed only and Custom tune vs. BAMA in same image) along with a simulated 1/4 mile run with the custom tune (11.643 @115.7188 mph with calculated dense altitude of 1659). Car weighed in at 3658 with 3/4 tank of gasoline and 3848 with me in it (weight used for dyno data and 1/4 mile simulation data).
Car has Steeda CAI, Kook's 1 3/4 long tube headers, Kook's 3" X-pipe with cats, Kook's 3" cat back, Shaftmaster aluminum driveshaft.
