I've been playing around with it for about a year now.. along with several other members. Nice little program. Showed 11 hp increase with my Eurocharge tune.. and have a base line on my Avalanche now just waiting for me to get my exhaust bolted up.
I'm not one to run down to a dyno.. so this is a great way to check improvements over "dang it feels faster".. LOL Oh that reminds me.. guess I need a zero to 60 run..
