Trex Dyno Numbers Are In!!!!
yea the graph is after tuning but i think im going to go back and see if there is anything else we can do to try na dget the numbers up i threw a code for fuel air metering so i will be going in to check that too.
Looks good.
You need to flatten out your AFR line, it went rich right after 6,400 rpm.
I do like how it started kicking after 4,500.
At 6500 it looks like it is making more then 60hp more then you had, and at 7,000 more then 90 hp.
What was your WOT timing set at in the higher RPM?
Did you try adding timing to see what it liked?
I think it should be 29 to 30
What size is the Y and cat back?

1 3/4 primaries should be fine for a stock-headed car. But all things taken into account:
4.10 gears ~8-10rwhp
Dyno reads low (Or rumor has it)
and the absence of the UD pulley which most full bolton cars have.
I'd say that your numbers aren't that far off from what they should be. Run'er at the track and see what she does.

you have no power down low, and dont start making until 5k+ rpms. theres only like 330 rwhp at 5k. thats no fun

Try taking the timing to 30, that cam is a big compression bleeder. I bet if you poll most that put down good numbers with that cam they are running 30 degrees and open headers.
Add some time timing and see how it reacts, then take it to the track.

why would open headers help? i dont know what exhaust hes running now, but that cam peaks really high, and makes all the power up top, but running open headers shifts the power band, so he wouldnt have much power down low if he did that
I'm more curious as to why you only gained 15 RWTQ? I agree it's running to lean as well, try messing with your AFR more on the dyno and see how your numbers work out. From previous dyno to this one the results are not that bad though.
I just pulled my Trex out and put a much smaller custom grind in, wanna bet on which one does better?..
