Default Do I need a tune after gear change?

I have a tune by Frost now. I'm getting new gears in spring. Going from 2.73 to 3.73. Will I need a tune for the new gears?

You will need a Speedometer Adjust. Thats pretty easy (tuning software).

I doubt gearing by itself would necessarily change your fueling requirement or load. May feel different, but my educated guess would be if your engines VE is not changing, just go with the mandatory 'speedo' change.

I thought all I might need was the speedo change. Just wanted to make sure.

Your shift tables will need adjustment too
