$50 is a great price compared to $125 but I still think it's a little too steep for a "Dyno Day". Ellis Autoworkz had a dyno day a while back and they were giving 3 runs with a/f and printout for only $20. The only difference is that it was only a 2wd dyno. I think if you lowered the price to like $30 you would get a higher turn around. Still a good deal though, I might come, just throw me an address.

Thanks!
