And for those getting into the #s, the accepted drivetrain loss on modern auto transmissions is around 12 to 15%, based on a dyno jet vs published oem. Results from a mustang dyno will show a somewhat higher % loss. But really, dynos are best used for tuning, and for comparing before and after numbers under identical conditions on the same vehicle to see if a modification has had the intended results. Dyno results from different units at different locations, temps, altitudes, vehicles, etc simply cannot be used to justify online "pissing" contests. I came from a high hp mustang world and some of the dyno result arguments could just get ridiculous.
But I am glad to see another tuner enter the game, since more custom tuning will be required when folks start modifying turbos, fuel components, etc.

Nobody was banned, please do not make stuff up. If you have to pay to advertise, then that's what I'll do. I don't use other companies to advertise for me to avoid fees, you have to pay to play. I also don't use other peoples vehicles to test on...again, you have to pay to play. If you know so much about me, then you'd know I pay to play.
