I thought so too. Made 690 previously, then 715 with the blowerguard (two different dynos though). BTR SC cam, long tubes, dual nozzle meth with 100% methanol. I'm not sure why they emailed me the graph in MPH instead of RPM, or why the axis are set so weird, but:

I used to drive 40 miles to come up and fill up on VP104 and C16 back in the day... now I live in town. E90 at the pump as well as VP 104.

Also, I agree boost sounds off, i bet you were upwards of the 11psi realm?
749/650 on ls3 A&A v3 Ti 3.6, AHR's back, Ethanol and Alky around 11psi, I do believe.

That much power on a 3.6" pulley sounds iffy to me also, but it at least makes a little more sense if the boost # is wrong and it has a blower cam, etc. i.e. not totally stock like I was thinking.

Oh yeah, with my current stock fuel pump I wouldn't consider not running meth. I do intend to keep the meth when I move to a Fore triple pump system.
And for reference to others asking, I daily drive mine pretty hard. I go through about a gallon of meth every couple weeks.
A&A V3 Ti trim supercharger w/ 3.6" pulley
Alky Control dual nozel meth kit
80lb injectors
BTR State II cam
Vararam Cold Air Intake
VMax Ported Throttle Body
Billy Boat Long Tube Headers
Borla Stinger Exhaust

Vararam with a blower? How does that work?

Or maybe I make more than I think, who knows. 165mph 1/2 mile with a shitty huge 4th to 5th gear ratio jump isn't horrible though.

Melting Slicks
I can't believe how many are using 100% methanol
optimal performance is typically found around 20-30% water, and its safer
methanol raises octane but does nothing for cooling the components inside the engine (piston/head regions)
If the intention is 'safety' then water is absolutely integral and kind of the main point of spraying in the first place.
In other words, you can raise octane any number of ways (C16 leaded racing fuel, methanol, toluene, ethanol, octane boosters) but the only thing that actually cools down an engine's internals (significant reduction in EGT) is the water spray component.
Water injection started as water injection (aircraft) which allowed increased boost pressure (lower temperature when injecting water). Thats how the whole thing started in the first place. It wasn't the methanol or fuel component, people just added that as an afterthought to raise the octane in the same stroke since it takes very little water to have a great effect, there was plenty of headroom leftover in typical pumps/nozzles, and methanol happens to be miscible with H2O.

You can't argue that it isn't working, though... the results speak for themselves.
Some around here do run 50/50 but 100% meth seems to be the norm.
I don't buy that there's no cooling from methanol though. Water may be better at it, but methanol isn't doing "nothing" either
