Also I'd like to add that I don't think manipulating fuel trims on a N/A nitrous set up is a big concern. However in a 2 or 3 bar MAP system with a blower/turbo this would be neccessary. I do however have an IR Temp sensor that I will use on each exhaust primary coming out of each cylinder to fine tune the fuel trims for each cylinder since my intake has been modified and the stock values are probably slightly off. However major adjustment to the fuel trims on my set up is not needed at this time. This of course will be done on a fresh set of spark plugs with gaps very carefully checked several times, etc.

O and yes Fred I have looked(with a fine tooth colm) over your documentary as well as LJ's and MUCH research outside of that along with trial and error with my own FJO wideband tuner and Tunercats and Datamaster and VE Master.
