Well, the truck is back on the road! I've been driving it for a week or so, working out a few bugs, and am very pleased with it's power. I'm still running the hybrid AFM, so I expect to see another power rise once I get the MAP sensor in place and properly tuned.
All I can say at this point is WOW. :-) This engine kicks some serious ass...and this is on a 140k mile stock bottom end, with it's "thrilling" 7.5:1 CR. The power band is much, much improved -- it makes good power at almost any speed, from just over idle to 5k plus. I've been shifting and lifting at 5k, but it feels like it wants to keep pulling well beyond that. I don't want to jump on it too much until I get the EGT and fuel pressure gauges installed.
One slight disappointment: I had to pull the Flex-a-lite fan and replace it with the stock unit. The 22RTE's have a slightly thicker radiator than the 22R/RE motors, and the extra row eats up all of the spare room between the fan and the bottom crank pulley. Oh, well.
