Ok boys im lookin for some internal pump work. Excluding Fuel plate, AFC work, DV, Timimg, and GSK. Im lookin for what calibration does ?? And if there is rack travel adjustments ? or what there is internally i can mess with.

Thanks

The only thing I could think of is a mac plug to adjust the rack travel(looks like you have to remove the pump to do this).Can't think of anything else.Would like to know what the pump shops adjust..

Being you have a 215 pump, you might want to skip the Mack plug. Too much rack travel will actually hurt fuel flow.

Oh alright, so lets say when you "send" your pump to a shop, what exactly is it they adjust or turn up? And im not sure i want to run bigger DV as i heard it makes the motor run very choppy. Any input on them as well ??
