I did 284/297 through an auto with MMR stage 2 heads/beehive springs/CMS stage 1 cams and regular bolt ons. Not sure on this new tune though, i'd expect a lil bit more.
I will tell you Thursday after I go to the dyno but I will not have LTs installed for this run. My tuner says he expects to see 295+ rwhp once the headers and X pipe are on.
