Thanks for the input Ted.

WRT the fuel pumps, are you saying both the Walbro and Supra TT pumps will mechanically drop right into the FC tank and mount up without any fabrication work? I assume I'll need to splice in an electrical connector? From a reliability standpoint, I'm thinking the Toyota pump is the better of the two. Another dumb question - is JZA80 the P/N for the pump, or is that just Toyota lingo for a Supra TT (i.e., as FC3S is for us rotorheads)?

I ran into those Venom injectors while searching the net; "too good to be true" came to mind, given the cheapo prices. Thanks for the warning! Looks like the Greddy 720's with the Bosch pigtails will do the trick for me. Given what you said about potential cold start issues, I may have to reconsider putting 720's in the primaries, after I learn more about how the RTEK works.

WRT the RTEK, what I gather from their website is that for fuel correction, they give you a 14x18 (252 points) RPM vs. boost table to play with, where each cell is a correction factor the user can set, in a range of +/-37% of whatever the corresponding stock map values are. I'm not exactly sure of what quantity the +/-37% refers to -- is it injector duty cycle, AFRs, or something else? More questions for the RTEK guys!
