I Had my 06 sr8 on the Dyno yesterday. Dont know what to thank. Took it to MODIFIED AUTO DESIGN in INDY. They used a DYNO DYNAMICS For the tune. With a predator Diablo. My Mods are CAI, FLOWMASER cat backs, I was only abel to get 306hp at the rear wheels. I know ther is a big diff between Engine hp and rear whls but just wanted see what others are getting. GOT NUMBERS.
