Yup, look at the numbers in my sig.
It is also correct that every dyno is different so it is not a good idea to bench race dyno numbers(my car has made between 275 and 293 on local dynos at dyno day events). That being said, I do believe that he should be making at least 20rwhp more than he did and possibly 35rwhp more.

I highly suggest taking it to the track for a couple of passes.

I wouldnt even bother worry about the trap speeds to determine the power, as the OP already mention the tuner said he "detuned" it because he thinks 11:1 compression is to high for 93 octane, so its not a matter of it just coming low on the dyno its coming low on the dyno because the tuner tuned to low.

Anything above a measly 16 degrees advance had it pinging like crazy. I mean it was spark knocking bad. The general feeling seems to be that I should be making more power and I do agree. I'm pretty pissed about the whole situation really.

My performance budget has been tapped out for now though. I think I'm just going to wait to get it back to FL to try to get it re-tuned.

Even though it was 93,? We only have 91 down here in az, and most local GT's are around 20*

What plugs and gaps are you running, a buddy of mine is running a built cammed b head 4v thats 12:1 and its fine on 93 pump gas.

1 Heat range colder (unless the guy at autozone screwed me) Autolites. And they're gapped at .45 if I remember correctly. I even have a colder t-stat in there.
