I can't speak for Bison, but in general, anybody's services can be bought. Question is... how much are you willing to pay? With that being said, an individual dyno session is likely to cost $1000/ hour. (2) cars could be $850... (3) cars $750... (4) cars $600, etc. That's why you need a few COMMITTED car owners to make a dyno session affordable for everyone involved ( Tuner, Dyno shop, Car owners ). Your price could vary depending on the # of cars, the dyno rental fee, the tuners fee, any applicable travel, lodging, and most important .. the amount of time your car requires on the dyno. My suggestion is get 4-5 committed car owners, find a dyno shop in your area that is willing to allow someone else to operate it ( not all shops are willing to do that ) talk to Bison about dates, times, travel, and cost. You can see again that this takes commitment, from everyone involved, so getting a deposit from car owners would be a good way to " lock it in ". For " gear-head" guys like us, this is always a fun way to learn. Throw some burgers on the grill, and make a day of it. BTW, you wont be disappointed in Bison's knowledge, but you have likely figured that out by now, or you would not be pondering this idea. There is a new thread posted in the REGIONAL / TEXAS section of this site ( you might want to follow to model your own dyno session), as we are planning to do this again in several weeks. Good luck!
