MBE 900 6.4L needs more power
Any experience out there with tunes for more power for the MBE 900 6.4. I have found a couple of programmer's for this engine. and a couple of company's that can reprogram the ECM and would like to hear if anyone has some personal experience for this issue. MY mileage is actually great getting 12 mpg even with quite a bit of substantial mountains climbing, but would like some more power.
