Weather report is looking good for tomorrow morning so FINALLY will be able to update with the new numbers. Will scan the dyno sheet and hopefully get a small clip tomorrow in the late morning early afternoon. Ordering up a new set of Invos next week for street duty but trying to figure out what to do for track tires. Glad the weather finally cooperated with me this week

Leaving now for the dyno tune, any last minute guesses on what the car will make? Hoping for 530+/500+!

car went back on the dyno yesterday and not exactly what I expected. I will be making a new thread in the scan and tune section to see if anyone can lend a hand on what may be happening up top with the car. Previously in october on the dynojet the car made 501/476, now the car is making 470/506 on a different type of dyno. The car is pulling noticeably harder down low and mid range but I can't feel it breaking up or falling off up top. Any ideas?

The torque looks right but I made more hp with my h/c LS2 so something isn't quite right. Wish I could offer some help. Judging by your location and the dynos you mentioned, I have an idea of the shop/shops you've visited and im sure they'll get it straightened out for you. You've certainly waited long enough.

The tuner is going to look at the graphs sometime today and will see what he says, just looking for other opinions of what it may be. Could be my springs possibly? Setup is SOOOO damn close to being where I would like it, just want to enjoy the car during the spring this season.
