Hi everyone

Well i spoke with Bill this morning and he had a file all ready for me to download. So we downloaded it and then plugged it back in the truck and still same failure.
Then you could see the light over Bills head come on as he at the same time did a face/palm move and said dammit i messed it up last night.

He said go back and re update the Gryphon, i put your old Stock file back on it that we already know doesn't work, instead of the new file i made lol.

Redowloaded the new Stock File and back to the truck i went. This time it WORKED AWESOME

The truck is hooked up with the 87 Custom Tow Tune and the 87 Custom Performance Tune woot woot

Now i can finally install my JLT Ram Air kit.

So the problem ended up being 2 things.

D2 error = bad harness from the supplier.

CheckSum Fail error - Stock File with the truck, eighter the old harness corrupted it or some issue with the stock check points and the upgrade checkpoints not matching up right for some reason.

Bill got it squared away.

Man awesome service and never doubted Bill for a minute that he couldnt fix it.

Thanks again to everyone who gave ideas and listened and hopefully this will help with other Ford trucks that have this issue and it will be a quick fix now.
