Got the z28 dynod. First run was 333.60 hp and 388.46 tq and second was 333.48 hp and 390.72 tq with the cutout closed both runs. It's really lean at WOT after 3500rpm and it's cutting out a little up top, which is why it's got such low power. The guy dyno'ing it said it would pick up about 40hp from getting it tuned right along with getting the correct a/f ratio. Graph and vids below (right click-> view image to see a bigger picture)

nice torque!

Thanks, I was really surprised with the torque myself. Can't wait to get it running right to get some better numbers and track times.

I must have missed you that day, I came out to the shop later on.

Here's my vid:

Its a 94 m6 t/a with just the ususal bolt-ons, it made 293 hp and 321 tq slightly lean all around...

Nice numbers out of your 383, must be some serious !traction with all that torque

I came out pretty early and left about 20 minutes after mine got done. I think I may have seen your car around here once or twice though. About the no traction...pretty much. I manged to cut a few 1.8s at Dorchester on old 235 street tires though. Any track times from yours?

Yeah i ran a 8.8 at 85 mph with a 2.2 60' which was my first time ever at a drag strip (Dorchester unfortunately)

not for nothing but you are really lean up top...leads me to think that it's not just a tuning issue but possibly a bad fuel pump.

Very nice numbers. Looking forward to the updated numbers when you get the air/fuel sorted out!

did your tuner tell you wy it was running lean? cause mine was doin that and i chased the problem forever but turns out it was my fuel regulator
