2010 SS 440 ls7 finally got my buddies 440 ls7 equipped 2010 on the dyno the other day. I need to post pics up of sheets, i'll do it asap. We were shooting for 550whp with the stock intake, and it dang near did it. 547rwhp. I'm guessing a fast 102/102 will help a LOT, it should pull close to or north of 7 grand, but falls off in the mid 6 grand area.
I will tell you its a pia already to tune these pcm's, and throwing a big ol cam and cubic inch motor into the mix was a fun 4 hour tuning session just on the dyno. I know it likes the heck out of fuel, it wanted 12.2 or more no matter what... Its a 440ci based ls7, stock intake and TB, 25x/26x .6xx 112 cam, cleaned up heads. Kooks longtubes, catted and kooks catback. Twin intanks, boostapump(for later) and 60lb injectors.
Who thinks closer to 600hp is where it should be also?
