the MAF is good since the stock is only good for 250 hp ..correct, but does it help if you have a couple mods on a BB which isnt over 250 hp, when i get my ecu reprogrammed i would rather get it programmmed first time throught with the MAF rather than upgrading later and have to get the ecu reprogrammed when i go over 250 hp...thanks

It won't necessarily help you, but like you said, if you do it now, you'll avoid the cost and downtime of upgrading later. Remember, though, past 250 hp the 370cc injectors will be either maxed or pretty close to it....

i forget, but do i need to have it reprogrammed for the new injectors too?..i don think you do , but i forget
