Stock whp on AT roadster?
Got a 2010 auto touring roadster n put it on a dynojet after all the parts were put on and uprev tuned. Made 308 hp. Anybody know what the stock whp is? I figured they woulda ran her prior to get a baseline but didn't. I've heard anywhere from 258-290. That's a wide jump! Anybody actually done it n have solid numbers. Thank you all for future references!
