I've been reading a lot of previous posts talking about SD tuning pro's and con's. I'm just trying to figure out if I should go this route. I will be going to see Allen in a couple of weeks to get a live tune and wanted to know should I stay with my MAF set up or go SD? I will be adding a meth kit as well before the tune. I don't have any tuning software to log or change tuning if needed. I heard that changing weather can play a big factor in an SD tune. What are everyone's thoughts/suggestions??
