Hi Mike. I wanted to check in with you and see if there have been any new tunes or updates added to the U7164? Please let me know. Thank you for your time.

Thank you!!

Should I see better mpg with the economy tune or the new performance tune? I've heard some of the higher hp tunes are better w mpg. I haven't tried the new performance tune yet so I'm just curious. Thanks.

Ok cool. Just wanted to make sure. I read on a forum that revs per mile was just for shifting so hearing from u makes me feel better!! Thank u very much!! Have a great day!!!!

Well I'll look again for the tire size. All I could find is the tire revs per mile. Didn't see anything for tire size change. Thank u for the extra tune!!!

Hey Mike. How many tunes does that update u sent me (9t18a) have? I thought I saw economy, tow, performance, and extreme? What does the performance one consist of? Also, does the tire revs per mile recalibrate my speedo or is it just for shifting? So far I'm loving it!! Thank u for ur time!!!!

Never mind. I spoke w someone on the phone there and they gave me the ratio. Thank u for all your help!! You guys have been very helpful!!!!

Thank you!! Worked like a charm once I figured out how to update the tool. Is there no option to change tire size with this tool? I saw the tires revs per mile but no tire size option? Please let me know cuz it would be nice since I've received two tickets in the last month. Lol. Do u know what tire ...

9r16??

Hi I have a 2010 F-350 6.4l. I just got an U7164 and I had a problem loading in the performance section. I received the following CALID numbers:
First unit: 8U7A-14C204-HCC
Second unit: 8C34-14C337-DC
Any help would be great. How do I find out what the current update on my U7164 is?

Thank you.
