So I hear mixed opinions?
A Ford tech says "no need to tune the car because the MAFS is calibrated to the injectors and everything should be fine."
Others say with this much work done, in my sig, I would have to get it tuned?
What do you guys think?

Maby a dyno tune would be in order. People have picked up some good gains in both power and drivability with aftermarket PCM's.
