Has anyone used Gtech to measure horsepower??
My brother ordered the oldest Gtech off ebay the other day, and we got it today. My dad has a 2003 ML55 AMG, and we tried measuring the horsepower, but it only registered 198...he was going about 20 then floored it to about 45 and the rpm's hit about 5500...do we have to floor it from a stop to get accurate readings??Has anyone used the Gtech and got the accurate horsepower number?? I know it's going to always be lower number on the Gtech though...thanks for any feedback!
