Aem uego, its not the wideband it is accurate we used my friends plx aswell just in case it was off but it was the same reading........I am posting my cal needs a bit more tweaking but it is the best I can get it to idle. Please check if you can, im pretty sure its the car but I might have missed something

Yes I know I thought it was weird to.... I called magnafuel and they said that regulator is only supposed to see boost and not vaccum off the charge pipe....anyways I put my stock rail,regulator and lines on tonight it was beter but when it gets warm it goes to shit when its cool I can idle it in the 14s???atleast now I can idle 13.0 afr when its warm.
