Martin, how you feel about tuning the FC vs an actual stock SR Rom tune? I've never ventured into the PFC, but its starting to look like an option vs a Rom tune. Though I know both are good either way you go, cost and easy of tuning are factors Im looking for. And of course it helps that my tuner(whoever they should be)is comfortable with tuning my vehicle initially and once I decide to change/upgrade. I was looking for abour 25-50 more whp but so far its look pretty good.
