Just got the V4 tune and also installed Kooks headers and offroad y pipe. Tune fired right up and seems to idle great. Only have a few miles on it as of now but everything seems smooth so far.

@svc with the V4 Tune do we still need to adjust the global spark table?
@svc ^^^^
You only need to adjust it depending on what grade fuel you are running. Keep it at 0 for 91 and up. If you run 89, go to -2. If you run 87, go to -4.

Coming from the diesel world, the tune didn't add as much power as it really helps with the driveability. So far I'm happy with it. Wish i could have gotten the intake to work with the tune, as i liked the sound and even got an extra MPG with it on.
Exactly my experience. Tune didn't really seem to do anything for performance. Drivability is better. Downshifts aren't where I want them to be. The good news is I don't really notice much of a difference when I threw the 37s on. Planning on doing some data-logging, sending to Jeff and see if I can pull more out of the truck.
When I tuned my 6.4 F350, the gains were enormous. I know I can't, but I wish I could get those gains out of the raptor. I actually very much believe my 350 would walk the raptor. Not from a dig but it would catch it quick.
