is there like a certain time like after you flash that it takes your car to start using that tune or is it instant.. and why is it that i make an adjustment in the maf for my maf tune.. and it is like it doesnt have any affect on the LTFT table at all.. also when you tune do you have to turn your PE tables to 0 when you tune?
and one more questions. when you do a maf tune do you have to do it like 4000-4999 5000-5000 and so on ?
