    351w 78mm turbo how much timing should be removed while making boost in part throttle. I reduced the timing in the higher load cells to give me 20* while in part throttle. While base tuning w 7 psi spring installed she makes 7psi fairly easily. I do have to push on the pedal a bit to get into boost but no where near wot. If I go wot the timing is coming off a different table which is working great I've been slowly adding timing back in on the WOT side and she keeps picking up. Dyno is coming up soon but I'd like to do as much as I can for driveability tuning. Is 20* on 7psi at less than wot acceptable

    See what the engine likes at any throttle or boost. If IATs are good and no ping leave the timing in it.
