The injectors were scaled before, havent seen a need to rescale them. The LTFTs are in line, average -4 to -6 part throttle, 0 at WOT. I do however question the status at idle, as I pulled my plugs today, and wow, they are soooo rich looking. So, maybe scale the VE down some more under 1200rpms. I went the basic ,400x60% then <800x80% and <1200x90%, went back and took all three lines down x90%. Plus messed with the IAC, RAFs and a little timing. Have it idling now at 750 much nicer than 900! I do a very slight bounce in as I come to an idle at lights, but it levels out quickly.
I used the predator, and the LSM Palm scanner, in conjunction with my wideband, and old skool, to narrow it down.
WicketMike has had the same problems, he ended up adjusting the MAP Min/Max values (edit 1.3) and it stopped his codes. I wasnt getting a lot of the P0121 code, but I did the same adjustment. No code and all day today been driving no deadspot. I am so very happy. Hopefully thats all it was, a problem with the PCM seeing a value in the higher than what it was set to see and somehow messing with Part Throttle take off. Again, I have put over 70 miles in it, more importantly about as many take off from stoplights, signs or just pulling over on the highway with no traffic. NO Problems.......*knocking on wood*
