I installed a diablo sport predator a few months ago and programmed my tire size in and placed it on the tow mode (level 1). Soon after I noticed a deisel fuel smell coming from the gril area after I have driven it for a while. I later installed U.V. dye in the fuel and found the injection pump leaking deisel fuel from the bottom area.

Has anyone experienced an injection pump leak after installation or is it just a coincidence?

Has anyone noticed all there fuel economy numbers are off in the trucks onboard calculations in the D.I.C. after perfectly installing the correct numbers?

I recently replaced two injection pumps due to a small leak on each of them. Both were 04 LB7's, both juiced. But I feel that it is a coincidence. Neither product raises rail pressure...

DIC will not be accurate with a tune installed.
Injector pumps on '04 LB7's, thanks for the warning.
