Using my ppe why would i want to do this?

like are you talking about disabling the timing before you upload the new tune?

if so thats just for when you dont want the tune u installed to add timing. good for when u stack tuners and programmers. that way ur not running to much timing. same way with adding fuel. i ran a ppe duramaximizer with my ppe standard and when i put the standard on a high tune, level 4 or 5 i would disable the "adding fuel" from the standard and just add fuel with the duramaximizer but i would still add timing with the standard
