hey guys. you've prolly all heard of these. the newer ones, SS & RR, are supposedly very accurate. the company claims within 1% of actual hp and torque when when the gtech is calibrated correctly. they also measures 0-60 0-100, 1/8's, 1/4's, and handling g's too which is all cool. i saw a couple older testimonies saying that the hp and torque ratings were a little generous but consistently so. and the 1/4 miles times were very close. these new gen ones seem to be really good if they can do all they claim. has anyone tried or know someone whose tried one of the SS or RR models?
