I have a 7141 diablo tuner I used on my mustang V6 5 years ago. That car is gone but I still have the tuner AND a 2003 Ford Ranger flex fuel 3.0L 2wd supercab. I'd like to tune the Ranger, is this possible? What hoops do I need to jump through to make it work? I want more performance and better gas ...

What would be the difference between the Trinity or U7141 for the 2010 GT Mustang? I see people using the Trinity but the store says the 7141 is the one to use.
If I have a choice, which one would be better (more control, more options).

HEY, anyone, if you want a tune and I mean a custom tune, make sure you check out Tuning Superstore. I can guarantee you will receive the best (no kidding) the best service available in custom tuning. I got a tune from Mike and I swear I thought he was my best friend. He knows these diablo tuners ...

What about the upgrade for the U7141? Is this ready? I'm told we should have cold air intake updates by now. I have a 2010 Mustang GT using Steeda cold air. Was told the update should be out now. Will pay for it without question. Where is it??? Thanks

Can you send me a tune to get me going again? I use the 91 octane performance tune with the Steeda cold air and the rest I can do myself. Thanks.

You may be right but I can not. Can only download the orig backup.
Device says I must flash the tool before going any further when trying to download last tune.

I use a U7141 on my 2010 Mustang GT. I added a cold air and want to get my custom tune to my pc so I can have you update the tune. I can only download the original backup file. When I try to download the last tune installed I get a msg telling me I must flash the tool at least once before continuing ...
