i am starting to figure this out. i have more than one problem and it isn't the rtv. the wideband still works, it is just the dash display part that stoped working, i can still log with the computer. the stock 02's heaters are not working, i suspect a missed ground, i checked the fuses.

i am out there trying to tune it with o2's that are only online part of the time

, i will be steping back a little and figure that out, then adjust the for the ltrims(if it needs it), then adjust for the WOT(if it needs it), then start in on the nitrous. sounds like alot of work but i do have a 4 day weekend

i predict a 12.4 gtech by the end of the weekend

hey, forgot, i didn't purge at all on that nitrous run. i did put in the 125 shot and did a hole shot and got a 1.71 60'.

I have my truck outside. It was about 54* outside and it takes a while for the O2s to warm up. Inside at 70* and taking 10 minutes to warm, you are correct, is too long. Also, I have an air/fuel gauge that I always turn on to find when I go into closed loop if I need to log stuff. From watching this gauge, the O2s read stoich and creap to rich before jumping all around. Nonetheless, good luck parish, that truck sounds quick.
