I have a few questions in reference to the Diablo Chip for the 2001 F-250 5.4L gas engine. First, I purchased my Diablo chip a little over a year age. Recently, my truck has been stalling out at highway speeds. Sometimes it would re-start right away and sometimes not. Yesterday, I had to have her towed to the local Ford dealer as she wouldn't re-start.

I pulled the chip out last night at the dealership, (before they even looked at the truck) and guess what. Truck started right up. My question is this.

1 - Could there be something wrong with the chip after it worked fine for a year. When it first started stalling, I removed the chip, re-sanded all of the contacts and re-secured the chip with Duct tape. THis did not help. Truck would stall out at various times and driving conditions.

2- Is there a re-flash for my particular chip and if so, how can I have this done. And how much?

3- If I have to send the chip back for a re-flash, do I have to pull the number off of the computer or is there a number on the chip which will tell what computer model I have. The following numbers are written on the chip I currently have...
M29F 4008T
7ON1 (not sure if the "O" is a zero or letterO)..
5886Y
0112

I appreciate any advice or information anyone can offer.

 

Give us a call on Monday at 770-806-1955. We'll swap the chip out under warranty and update it to the latest code for free. Sorry for the problems, actual hardware failures are rare and we'll get it taken care of as painlessly as possible.

 

I just wanted to let you know that I called the store today and spoke with Jolene. I explained everything to her and she was wonderful. She provided me with the information I needed to return the item. I just wanted to let you know how helpful she was and how much I appreciate it.

Once again, Thank You very much...

 

I told Jolene what you said and you've made her morning! I'm glad we could be of service to you.
