Very true about the starting fat. But with a fresh efi system with somewhat educated guesses about starting lb/hr injectors, base fuel pressures, the bsfc of the modified motor, and an unknown timing curve. I will end up frying a couple sets before it's tuned properly.
I ended up buying the yammy skid. And a few other goodies. It's a proaction 136 skid from a venture. And I got a 141" proaction skid from a mountain max, a nearly brand new camoplast 1 3/4" track, a pretty unique phazer pipe that I've never heard of, and a set of 38mm flatslides. $300 for the whole lot. The track was worth that so I couldn't turn it down.
