Does upgrading your heads require a tune?
If you put aftermarket heads on will it require a tune to idle, race, and drive properly? With my limited knowledge I am guessing you don't need a tune because the MAF meter measures the air coming in and adjusts the fuel accordingly.

i think you would just be able to reset the computer by unplugging the battery for while and let it learn by itself...not sure though
