Here is what I need from a tunning program. My main need of a program is so that I can set my A/F ratio in incraments of 300rpm or so. Will both do that. I need also to deaden False Knock. (I have an Lt4 KM and insulated it. Pllus I want a program that will allow me to customize a lot of stuff.

Oh ya and for those with a mech. fuel pressure gauge do you run yours all the time? or are you afraid gas will leak and start a fire?

Thanks
