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.

Good news, man! I haven't followed the entire story, but Is this an SCT tune I'm assuming?

So you lost about 100whp by switching to a better tune? Was the 625 supposedly on a conservative tune as well?

Yes, SCT. It's crazy how all over the charts things are, I'm really surprised the car ran as well as it did. I guess WOT isn't all that hard to tune for? LOL!

The 625 was a "Glory" run, done I'm sure completely for my benefit that day at the shop. It was loaded with extra timing and actually ran like shit. The tune I drove out on was closer to 575 and it was a bit more conservative. It drove pretty decent too. Looking back at it now, if the car can run 10.80's at 575, and I can have it driveable at that power level, I think I can live with that.

Definitely. I would just think that if 625 was attainable on a crappy tune that, a good conservative tune could yield 600 easy. But you would know better than I. You're in the 10s already and I am still bone stock lol.

If we can get 600 and still be daily driveable, believe me, we will! I"m just saying I'll be happy with 575. Hell, after all the crap I've gone through, I'd be happy with 550! LOL!

Glad to hear things are going well bud. I sure hope Travis can get it dialed in right!

550whp is a damn fun street car I'd imagine.

Good to hear it's getting some progress. I'm going to hold you to your word about going to the track together and see what we can do! lol.

Trust me, with 575 to the wheels you have plenty to brag about.

Sounds like a plan to me! I need to get out and get some track time anyway. Hard to believe, but it's been close to 25 years since I've been down a legal strip around here. I usually drive at least 4 states away when I race.
