Looking for a little info here. I have a 2500 4x4 with a 5.9 CTD. I went to NADP in Edmonton yesterday looking for a programmer or module with hopes of gaining a little more power and most importantly some additional fuel economy. They recommended a Predator Stage III which they installed at the dealer. I was told I could expect a 2-4 mpg increase with this module. I drove the truck 900 miles yesterday and today driving on cruise at 70 mph the whole trip. My fuel mileage went from low 20s before the module to less than 17 with the module. The truck has quite a bit more power but the check engine light came on at about 700 miles and has not gone off. The truck has 11000 miles on it.
My questions are as follows:
1. Should I actually expect a fuel mileage increase with this module?
2. *** is with the check engine light? Would the module cause this?
3. Did I buy the wrong module?
Any advice would be appreciated!
