“Don, I didn’t have the chance to commend you how great your Crew Chief 7.50 was for me. In my first season using it my father and I finished 1st and 2nd in our Heavy ET/Foot Brake class and 1st and 4th in Super Street at our local track. It was so successful that we won 6 of 11 events that we completed and were in the finals of 8 out of 11 in our Foot Brake class. This system has been far superior to anything else that I have used and has already paid for itself in just its first season.”

“Don, UNBELIEVABLE!!! That’s the word I would use to describe your Crew Chief software.  While making your rounds @ Z Max last weekend, you asked if I had any questions regarding your Crew Chief Pro software….my answer was a simple no. Well after using it the entire weekend, I do have one question for you! Is it LEGAL??? I’d like to keep this Wally they gave me for winning S/G. lol. I might eventually start dialing honest! Haha…just kidding. Thanks for providing such a quality product!

“I just wanted to tell you that we ran the car in Super Comp at Fontana one weekend and ProGas the next weekend. In Super Comp we made one qualifying run on the 8.90 index and ran a 8.910. During eliminations we ran three 8.90’s. The next weekend we ran the car in ProGas and qualified with a 9.901. Ask me if I’m happy………go ahead……..ask…….. You bet your ass I’m happy!! Thanks Don !!!”
