No you just need to tune the VE table.
yup.
12AFR /13.8AFR = .86 what i would multiply the VE table by. now when we leaned the fuel it pulled better vacuum moving the area of the VE table we need to target...
You could also just run VE analyze....
Ok looks good, now using that tune drive the car using Auto tune and let it do its thing for a little while on normal.
