I used zchem to scale them and saved right afterwards, and at wot whatever I do it wants to run lean on me. My poor Weisco's...I tried increasing the injector cycle but it only helps a smidge. Besdies a new fuel filter any suggestions?

What scaling factor did you use? +40's should be 65% (34/52) NOT 60%...

Oh, that's right. He had it setup to do it automatically by injector size. You can post it if you want, I'll try to take a look at it...

No 'insert file' option. Is all I need is the wot points scaled for +40s up to 30psi, pretty sure there is only four points. Is it possible the tps isnt throwing the required voltage for wot, what voltage indicates wot...thanks again for helping.
