240-260 is still shifting at 70-80% there. Add 5 to the 240 and 260 rows. With wheel spin I bet you hit that area. Are you experiencing slip? If so, you can subrtact 5 from the force motor table from 132* to 240*, in rows 60-90%. Subtract another 5 in those locations if it still fells like its not grabing. You install a shift kit when you built it? If not, pretty sure one can be installed with a pan drop.
Over 80% in our fueling systems is static. The injector cannot open and close fast enough to feed it properly man. One step up is all you need, nothing crazy. Too big is a p.i.t.a to get any kind of idle out of.
