Disappointing Dyno Results
Looks like it peaks torque a little early. What intake centerline was the cam degreed in at? Assuming you degreed the cam that is. Numbers look pretty disappointing to me sorry.
That's more like what I was expecting. The car club I joined is having a dyno day this spring, I might have that place take a look at the tune and see if this guy f'd it up.
Seems about right for the mods you've got and where the pull was stopped. A FAST intake would definitely wake it up a good bit more, but she looks alright to me all things considered!

By looking at the graph and the pull being 1500rpm to 6000rpm makes me think that it was probly done in 3rd gear too which brings down the #'s. I have no idea why the pull would stop at 6k rpm unless there was a problem.

depends on tuner i have seen them done in 3rd and 4th..
dyno numbers seem pretty good, i would have thought 420 with a m6 but if it runs good y complain...its just a dyno number..we have all seen a car with less outrun a car with more...

Dude, I have damn near the exact setup as you. Everything is the same except the pump, injectors, and termostat. Mine are all stock and I have stock 241 heads and my car made 403/392.
You still have room for more in it. The intake for one and the stock massair. I gained 9hp just going from a stock massair to a gm 85mm unit. You have another 25hp you could still get. It made good power overall. I'd be happy.
Dynojet, at Backstreet Performance here in Medina, OH. Now its throwing a P0135 and a P0153 for the O2 sensors....he was supposed to tune out the rear ones I deleted...Are these codes caused by the missing ones or the ones still in place? Seemed like it was stuttering or missing on accel here and there too today. Now I'm just more pissed about this tune (assuming that's what caused this too...).

I'm gonna swap back in the stock injectors and the pcm I have with a stock tune and see how it runs and if any codes are thrown. If not then ill talk to Eric and see what's up with the tune.
