Ok so i am waiting on my tune to be built and was wondering what to expect? I have recently add: ford racing heads,BBK X-pipe w/cats,flowmaster delta 40 catback,BBK CAI, BBK 75mm throttle body. I am just trying to get some feed back while I wait, I ordred the 91 torque tune. So i am wondering if I will see a big differance in the performance?? anyone ever have the tune need a lot of tweeking or was it good to go roight out of the gate? i am hoping mine should be done by Friday.
