Help find the missing RWHP : 408ci, M6, 9" here is the graph....each time hp went up. a few things to note. the car is a full bolt on car, Fast 90/90, 30# Fast injectors, 257/266, .622/.642, 113 lsa cam, PRC stage 3 heads, ASP pulley. Headers are Grotyohan 1-3/4" Long tubes, 3" into a Hooker Aerochamber. he dual cutouts are in the y pipe.
Motor has about 1000 miles on it, also with a new 9" installed at the same time. Fuel pressure is fine as the AFR is pretty dead on, and last run i believe had 28* of timing. I am throwing a code or 2, 1 being a misfire that i believe to be my drivers side o2(awaiting my extension to install new o2), and egr code, and maybe a TPS code(p0121).
im thinking theres more there with more of a break in and some more tuning(something broke so we had to quit for the night), my tire pressure was pretty damn low, weather was about 88*, ~56% humidity, and ~30.07 barometric pressure(i think)
help....

What psi are those fast injectors rated at?
Were the dyno pulls done with the cutouts open?
That's a big *** cam on a 113 so it's going to want rpm but your peak is fairly early. I'd like to see a graph of the manifold pressure to see if you're pulling vacuum up top.
If there's a tps code are they sure the tps is reporting 100% at WOT.
When you say you quit early because something broke, did something break on the car or on the dyno?

the lower pull was through the exhaust(453rw) the higher number was cutouts open(481rw).
TSP mentioned it should peak around 6400, my rev limiter's at 6700.
hmmm does WinPeP 7 have a map overlay? i havent used it that much.
That TPS @ %100 comment makes sense, ill have to ask the tuner...
and nothing broke on the car, the handheld xcalibrator that loads the tune overheated when someone was messing with the battery, so it wouldnt read anymore, we just couldnt tune anymore.
i also posted this thread in the dyno section to get some more views...

and Patrick G, thanks...i appreciate it.
