I have, it was $80 for 2 pulls or $120 for the "Dyno Tune" and the 2 pulls so I'd say your price is pretty good.

Everyone around here says it will cost at least 200-250 for 1 dyno pull. I need to start doing some research!!!

390 at the flywheel, not too bad for a sbc.
$250 for 1 pull? whoa, that's steep. I don't think I'd want to find out that bad. |

Exactly why i haven't done a dyno tune, which is what I really want to do.

how big of a difference is there between flywheel torque/HP and rear wheel torque/HP

The best I could find is this.
"The difference between flywheel horsepower and rear-wheel horsepower will vary from vehicle to vehicle, depending on many factors," adds Gale Banks Engineering, "but we find that rear-wheel horsepower is usually between 18 percent and 25 percent less than flywheel horsepower." It depends upon which transmission you use. Most manuals take about 15-18 hp Powerglide.....................15 hp TH350 .........................25 hp TH400..........................35 hp 700R4..........................25 hp Then you have the loss through the Ring & Pinion, Brake drag, Tire Size/Weight |
