Well, I have some concerns with the rear end. I just got a 2 step that I want to get in before going to the track. But, that also means the rear end has to go. I just don't feel like towing the car home. Besides, the turbo is right next to the rear if it blows!

standard 60-1. Completely stock motor. Considering the work that's done, I think the numbers are pretty impressive. Injectors, fuel pump, intercooler, base STS kit. Once I get the rear end swapped out, I may do some motor work, but I want to get the most out of the stock motor first.

if it were me I would richen that thing up. I would be afraid of leaning out on the street/track to dangerous levels and kissing a piston goodbye.
remember the difference between the dynojet and the street is at least a 1/2 point A/F wise.

I agree with what ^^^ said... That is on the lean side... I know lean helps spool up, but try to richen up in the upper RPM's. Also why do u have less TQ than a N/A LS1 around 3K rpm? When do u see the full 8psi? Looks around 3500rpm.

Thanks for the feedback guys, I'll definitely keep that stuff in mind. I haven't driven the car too much yet since the tuning. But, I'll keep an eye on the A/F for sure. We were seeing full boost by about 3600 rpm. As far as lower tq than a N/A car around 3K, I have no idea about that, wish I did. It's possible the car could have used a little more timing down low, but we didn't want to get carried away.
And the shopping list is growing...rear end, now headers & valve springs!!

Anybody notice that the graph on STD and not SAE? I thought the real #s on on the SAE scale? Great #s though! Who did the tuning? What did they use (edit or hpt)? The a/f looks good (meaning a straight line) but you should def move it down to like 11.5 - 12.0

The turbo could be choking out at the upper RPMs too. The 60-1 is great for 5-6 PSI but at 7-8 PSI the GT67 upgrade will keep the curves up till redline. We could swap out your 81 exhaust housing for a 96?
Awesome numbers though for a stock motor and 60-1!
