If anyone picks this up (decent deal, actually) - don't forget to use Goods and Services or pick up in cash. It's not that @A91CFSupra isn't trustworthy, but this is the first post on the forums.
Trims lower more consistently. The meth is getting atomized better and further back. What I didn't try was 1x 1000cc nozzle in the location closer to the turbo, might have had similar results. With the 2x500cc nozzles I'm getting very very consistent trim graphs. Under WOT running E40, trims up...
Yeah - we literally all are. I run E40-E50, but I balance trims with meth. You can easily run E30 with JB4 and no fuel system upgrades. No flex fuel kit here. Just measure out the fuel, and away we go. Trims, AFR, everything is very healthy.
