  "Because I run a Blown, Nitrous Mustang, I tunned the car for a rich mixture. When I bought this Meter, I found out that I was way too rich. Leaned it out to the right figure and picked 38hp and my EGT actually went down. Extra fuel was burning in the header at the EGT location." 1000hp Racer in Calf.

"Phil, the owner at The Dyno Shop, shipped the unit the same day I ordered, and was available by phone the next night at 8:30pm when I had a few questions. The unit is easy to use. I made 20hp more." Racer - Tunner in ILL.
