I have tunes on my computer, one of which is the original back up and it is not recognized by to tool. The file has a CROM extention. When I open the downloader tool on the desk top, go to advanced, send tune file to tool, the browse window opens but there is no option to find files with the CROM ...

While plugged into my PC, I saved the orginal backup on the PC, following the predator prompts.. Months later I tried to restore my truck back to original tune and the predator could not find the tune. It must have deleted the file stored on the device after downloading it to the PC. I had forgotten ...

I have a tune on my home computer from when I originally installed the predator and am hoping this may be the original back up. awhile back I tried to install the original tune off the predator, it would not work and tech dept had me use the stock predator tune instead. I noticed that all the ...

It was about a year ago, check with the tech department and let them know to correct this reoccuring issue the right way.
letting them know that this is an issue with many others should get them to find an answer asap.

I too had the same problem. Tech support said to install the stock tune from the predator. What a disappointment that was. Went from 17-18 intown and 21 hwy(1750 rpm with stock tires) to a dismall 16 intown, 19 hwy. Knowing others are experiencing the same issue, it now becomes apparent that the ...

Johan, quick fuel economy question. I run a basically stock 2006 4x4 and use the street perf tune. One of the obvious changes is the increased turbo performance. If I customize this tune: less turbo boost, would I see mabe 1-2 mpg increase?

Does Diablo offer a custom tune for fuel economy that performs better than the performance/economy tune that is on the predator? I am intrested in in maximizing fuel economy.
Thank-you, happy thanksgiving

Are you in an 05 or 07 5.9 CTD? On an 07, you may want to check your EGR valve. They are a big hassle and stick alot. Thats why I bought an 06. Hope that helps.

I would like to know exactly what mods other than the predator you have installed. The reason being that my 06 never surges with the predator, I have it set on econo/perf and ran it in tow alot. It was 28 degrees this morning in ga and it started right up and ran smooth. I dont even use the idle up ...

In the qwest for more economy I came accross a module that plugs into the the fuel pressure sensor. If I am using the predator in economy mode and then use this module would I reap any benifits of the 2-3 mpg that the module claims or just wasting time/money??
Thank you and HAPPY THANKSGIVING :wink:

Can someone at diablo find time to recalibrate the overhead computer so it is at least close to accurate reporting mpg? My truck actually was very close to accurate when I bought it new in 06. Ever since I have installed the predator its been way off, even after going back to what was suppose to be ...

it actually was better with the tow tune. I dont trust the overhead computer. If the the over head was accurate i would get 25 mpg, I wish!! The 2 1/2 better mpg was in comparison to the eco/perf tune. For me that was the better of the tunes. Currently my mileage has dropped a lil, mabe a new filter ...

I'll go a giant leap forward for future possibilities. Dodge and GM both have started incorporating a version of cylinder shut down on V8's to save 25% on fuel economy. Dodge could incorporate a cylinder shut down in the diesel. I wonder if 2 or 3 cylinders could be shut down. In the 3 cylinder ...

8) This topic has been brought up a couple of times, even by myself. (see previous thread by tiger094) The over head computer is off by a few mpg estimates with the predator installed. When i had stock tires and tune it was right on. Must be a percentage written into the predator program thats off ...

In an effort to diagnose the intermittent miss, I have decided to data log in hope catching the miss in action. I have a couple of questions on Data Logging. 8)
:?: 1: Does the predator have to be connected during this entire process?
:?: 2: What parameters for this specific problem do you ...
