Last Cummins I had (05 model) ... I had the EZ. Under hard acceleration, I started to feel the tranny slip. Plus, after 2 injectors, decided to go back to stock. Back then, there wasn't a product from Diablo.

Prior to the 05 Cummins, I had a PJ Ford and the Predator programmer. After spewing coolant everywhere, I took that off (bad headbolt design by Ford).

I am looking for good reliable low-end power and as few as possible signs left if it is removed.

So, what is the general concensus these days ?

Predator programmer

I really like my Predator and Diablo swears it doesn't leave tracks. The 100 hp runs really nice and bottom end is good - 1200 max egt. The extreme program is VERY strong at any rpm - 1350 max egt. Extreme is a little wild to run all the time but mpg has been the same as the 100hp/economy program. Driveability is great and no codes on any program. Craig
