*Remove DPF/EGR
*Downpipe
*Methanol
Anyone with this extreme of a combo in the US yet?

Yes, yes, partial (DPF section gone, DOC section still in place), and yes.
I've got some info on an Evolve remap with and without some custom stuff which includes 50/50 H2O/methanol at ~650ml/min max level (so Hotrod was squirting ~4X the methanol in his runs). Also has the charge air temp data and EGT's with the runs. It was on a stingy Superflow dyno with their largest rollers so big dually pickups can be strapped on it...

With the pre DPF/Ecotune mods using Evolve and stock IC/DPF this everyday methanol/custom/Evolve setup, along with some slicks, I've done 12.65 secs and trap speeds of 110.18 in the quarter mile with less than ideal winds/DA's. The Ecotune/DPF mods have freed up about about 20hp more according to my rough measurements using my in car measurement devices.
