Just wanted to let everyone know that we are compiling the information gathered from the Engine Failure Survey now that that I'm back in the office. http://forum.gopowerhungry.com/image...p%20yellow.gif

We are in the process of contacting the tuners listed on the survey to find out the number of files they have tunes they have in service, so that this information can be part of the final data.

We are also contacting survey takers by e-mail to ask them two additional -- very pertinent! -- questions that we realized should have been included.

http://forum.gopowerhungry.com/image...youflowers.gif for your patience!

We will leave this survey open until the data is posted so that anyone else who has experienced an engine failure can add his/her information!

The survey can be accessed HERE.

Any news?

Just filled out the survey, but might have submitted it twice.......oops.

Trouble Maker.

No diesel for you... One Year!

We released the results of the survey to the public for a month or so and then closed it due to the fact that people were manipulating the results in various posts. This was merely to obtain information... not to lay blame, yet certain forum members chose to use it that way in defense of their favorite tuners or to point fingers at others.

Below is the results of the question you're looking for. We know that there have been hundreds of engine failures and don't even remotely think that our results encompass everyone that has experienced engine failures on a tuned truck. We posted links to the survey on many different forums and encouraged people to fill it out, which is the best we could do. We do feel that this is a good snapshot of the industry as a whole.

Bill has spoken with many tuners about the results (there were more than 20 questions on the survey), and this sharing of knowledge has helped make calibrations safer for the general public. We know for sure that one particular tuner has taken a lot of timing out of his calibrations, and that's a great thing!

Keep in mind, of course, that only a limited number of people responded, so here are the results based upon 56 responses:

Which company programmed your truck?
DP-Tuner - 35
TS - 5
PHP - 2 (this should really be a "3" since Bill does Edge's tuning, as well)
TDP - 2
Diesel Innovations - 2
Superchips - 2
Western Diesel - 2
Bean's - 1
Gearhead - 1
Swamp's - 1
Innovative - 1
Edge - 1
Bully Dog - 1

We asked many of the companies in the survey if they would like to provide us with the number of tunes they have in service -- this is NOT the number of customers nor the number of chips sold. I have listed them in order from greatest to least.

TS Performance (Dennis) - ~600,000 (Dennis was unable to determine the number of programmed chips sold since 2003, so this includes blank chips as well)
Bill - ~164,000 (includes Superchips (1998-2000), Diesel Power, Edge, and PHP; since we do not own Superchips or Edge, we are not at liberty to disclose exact sales figures for either company)
DP-Tuner (Jody) - ~60,000
Diesel Innovations (David) - ~12,000
Total Diesel Performance (Tony) - ~6,000
Swamp's Diesel (Jonathan) - ~6,000
Bean's Diesel (Jonathan) - ~800
Gearhead (Matt) - ~780

The survey, BTW, is still open, and anyone who has experience engine failure is welcome to fill it out.If the data changes significantly, we will happily make the raw data available again.
