I have a preditor programmer, and I'm going to be putting on the zex 75-100 shot, with the programmer should I do motor wise? Retard the motor, rich or lean it, I won't make to drastic of changes just minor that might help

 

Get a dyno tune.

 

After buying that stuff I'm out of money for awile, thought this would work for now since I have it.

 

Oh, sure it'll work....but I have to say I wish you the best of luck. A dyno tune is not just about adjusting your timing. They can tell you how lean or rich you are running, where you have no way of telling. Unless you have a wideband A/F meter laying around. I STRONGLY suggest a dyno tune.

 

im running a 125 shot untuned. obviously i will get it tuned in due time from a dyno shop. i have my cars timing retarded 4 degrees for the shot. you should be fine with the stock timing with a 75 shot or maybe retard it 2 degrees.

 

I got the air/fuel guage, bought it when I ordered the nitrous kit.

 

those things don't work to well unless its the $400 dollar type one
