Default Update on my car

Finally heading in the right direction. Travis has had it on the dyno for the last few days, trying to get some baseline readings and figure out what was going on with the car (it wouldn't rev, sounded like it was choked off, the weird idle issue, the miss, all that crap). There was no smoothing the original tune, the parameters were just all over the charts, nothing really made sense. The 80 lb injectors were scaled back to about 55 pounds, the fuel trims looked pretty good, the timing tables were all over (probably why I made 625 to the wheels). I told him to just start over and see what he could do with it.

Talked to him today and it looks like we're getting close. He started from scratch and it's idling more normally, revving free like it should, and the miss seems to be gone as well. The initial numbers, on a conservative tune, are 550 hp and 515 torque. Much more inline with what the car should actually be making, given the fact that I'm still running the base pulley and stock throttle body. We may swap out to a set of GT500 injectors to see what they'll do (the '13s came with 55 or 57 pounders). I feel confident that we'll end up around 575/520, and I'll be completely happy with that, especially if it's daily driveable smooth again.

Travis is going to be out of town for the next week, so I'm having them do the other little odds and ends while he's gone (look at the clutch, replace the off road x with a catted x, etc.). Hopefully, by the second week in September, I'll have her back and running good.
