It would be nice if the Mirage a shift up indicator like a lot of manual transmission cars have. Everytime I get in the Mirage and drive (like on the weekends or store trips) I notice the wife gets like low to mid 40 MPG's, but everytime I drive it I get high 40's to low 50's

I figured it out one day when letting her drive while I rode shotgun after a few beers. I noticed her going 55+ mph in 3rd gear and I corrected her like 4 times on the ride that she needs to upshift. Wifey is hard of hearing and does not hear the engine screaming at 4K while cruising down the road. I decided to remove the intake air snorkel to make the engine louder and this seems to correct the issue, but I would rather have an upshift indicator.
