ive never used a lean out, only used timing for wheel speed, so maybe I'm out in left field, but I would like to try to add wheel speed at a certain point in low gear with a lean out. Based on flash vs fallback, and what my converter guy said (shouldn't be that much lower on flash) I'm assuming I have too much fuel early in the run. So, if I want to add wheel speed at .xx in, should I open the leanout at .xx -.1, .xx -.2,?? Would it tend to ramp in power or more like a light switch? Also, I'm thinking I should shoot for a little less than 10% flow change on the leanout. 15 gallon pump with an .081 main. Thoughts on a starting point?
