A customer/friend has an '05 4X4 conversion van with a 6.0 in it that needs a little more power for pulling his race trailer around. With the stock calibration it only puts out 20 lbs peak boost. I tried downloading cals from an '06 F and had no speedo
; used cal from an '04 F and ended up with no glow plugs or starter crank when trying to start
. Both of these made around 30 lbs of boost so hoped I could copy their calibration, but neither worked out for me. Anyone know of a calibration code that will add more power without chipping it? Thanx, Mike
