Problem is that I don't think there's much left in the tuning, take a look.

Pretty much dead on!

This is the only run that picked up the RPM signal the whole time.


Here is all of the runs

Damn I guessed 355hp at 348 torque. I was right on the money with the torque!

Very nice. Enjoy it, you went through a lot of obstacles to get there. :cheers: :cool:

When are you getting to the track?

Was gonna go to the track Tuesday night, but that might change.

I want to go, but I got FREE tickets to the NHRA finals in Indy tomorrow. After driving up there Monday early (2 a.m.) Watching the races and coming back I'm going to be dead Tuesday so I don't want to go to the track half asleep. My tranny wouldn't appreciate it.

I must be blind. To me it doesn't really dip, it just doesn't really grow. It doesn't quite make the low end torque of the L98, but it sure makes up for it fast.

It really feels good. In all my mods I haven't lost any torque and have basically added 100 hp over stock. I couldn't be happier.

I think I guessed it dead on right? I think I posted 365 and 345.

yeah it looks like there's not much to tune. The A/F ratio is almost perfect. I don't think you'll squeez anymore out of this setup. Dyno tuning is expensive and I don't think $250 an hour is worth 5hp.

Very good numbers.

:cheers:
