6.0l Chassis Dyno Numbers

[Racingduke]

I have a wait4me ECU on the way and plan on going to the local chassis dyno to see the REAL difference in HP and Torque vs. the stock ECU. I am wondering if anyone else has gone to the chassis dyno with thier 6.0L after performance mods such as; air intake, exhaust, handheld programmers, programed ECU (wait4me and webster), intake manifold, throttle bodies.......etc? What did you do and what did it do for your truck?

Justin told me my tune added 30-40 RWHP depending on the truck. He's dynoed a bunch (though not mine specifically) and that's what the exact gain is. Everything else is bone stock. I figure I'm closer to the 30 since my driveshaft is a mile long-I have more room to lose power through the drivetrain.

 

No MPG gain-I don't care about that. I justy wanted the most aggressive tune.

Please explain to me how a long driveshaft costs you power? On a class eight, the gear train loss is 18%, you get 82% of engine out put to the ground. PLAY SAFE!
