RPM dropping

[FarFromLosin]

Hello, I have a 2015 ST and notice while driving on the highway in fifth gear my rpm will drop to about 1000 before springing back up doing about 65mph usually. Has anyone else had this issue or anything else like it? MODS if this is the wrong place sorry in advance

Do you have a Cobb Accessport?

 

[FarFromLosin]

Yes, I do. Sorry I forgot to mention. Im on the "stage 1" 91oct tune

A few other questions... Are you enabling/cancelling cruise control when this happens? Or touching nothing at all? Also, more for curiosity, why are you cruising 65 in 5th?

Actually yes I am canceling cruise and it's six not fifth must be the sinking getting to my head. Maybe it's something to do with the tune?

Sounds like the result of map switching... there was a glitch...

Yep ^^ It's the map switching "menu." Read up on your Accessport some more.

The new update fixes the issue, so update your AP.

Are you saying it slows down to 21 mph (1000 rpm) and then speeds up again or just your tach drops to 1000 while maintaining 65 mph?

+1 it's the map switching menu.

Keep in mind you must re-flash your tune after updating firmware.

Yep it sure it the map switching menu. It was only My tach and it happens at any speed in any gear when I push the cancel on the cruise. I was kinda worried but thanks to you guys I'm at ease about it. Thanks everyone
