Sure, he can do a regular dyno run, but he can do much more.
 
If you had a DME, he could emulate a chip so can make rapid changes while the car is on the dyno. On my race car, he found multiple issues including a board that didn't match the DME box, and a chip that didn't match the board or the DME (or my engine), and burned me a new custom chip. 
 
He also found issues with my injectors, fuel pressure regulator, wires, and more. Parts were not cheap and labor was typical P-car range. Chip bought me 15 HP. The other stuff another 7 HP. Total increase >10%!! Yes, it is noticeable.       | 
	
 Hey thanks guys for all the responses. Appreciate the info. I am a little old skool and Word of mouth is the best way to do business. 
    Yeah this wheel based dyno is exactly what I was looking for as its more accurate than the standard roll-ons. Plus like you mentioned its a lot better at tuning from the reasons you stated. Its just not a lot of guys have such a set up. 
     I will check him out and start saving my pennies. 
thanks again,
Fred
