Z06 dyno'd, It needs tuning! My GF had her 2001 Z06 dyno'd this past weekend. (it has 6k miles) It has a Blackwing and FLP's w/no cats. The A/F is weird. It starts lean, richens up, then gets too rich, leans out, leans out too much, then starts to richen back up. It did 361.3hp and 356.6tq

LS1edit is in the near future. I'm thinking about 10hp more once I get the A/F ironed out.
Thoughts?

Re: Z06 dyno'd, It needs tuning! There is definitely power there in the A/F (6-9) would be realistic). Did you happen to log timing and KR? If there is anything we can do for you let us know.

Re: Z06 dyno'd, It needs tuning! Yes, I did a data log with EFILive. There wasn't any KR at all. Initially, the timing dropped to 17ish deg then came back up to 22-25 deg the rest of the run. I can get the exact numbers this evening when I get home. Thanks for the input.

Re: Z06 dyno'd, It needs tuning! If you would like to forward me the EFI files I can take a look at them. I've got EFILive so I can view them natively. Correcting the A/F ratio would not be difficult at all. As for timing the car could most likely tolerate another degree or two in the upper end without any issues.
