Gear upgraded, 3.08 to 4.10
I just upgraded the gear in my Suburban from 3.08 to 4.10! Still need to go to a speedo shop to get the speedometer calibrated. First drive today, it's feels quite a bit more responsive though it's...

Since you need to get the speedo addressed, why not get a custom tune from Black Bear? That will really wake up that 5.3 especially with how well it will change the shift strategy!
Bingo! Could not have said it better myself. I have the EFI Live tune and love it. The tune is worth the time and investment to look into it.
Okay now I'm curious. Other than shift strategy, what else does a Blackbear tune do? I don't want to use higher octane fuel. Right now I use 85 here in Colorado.
You can specify any octane you want. You will only gain approx 10-15 HP same for TQ. Nothing to write home about but it does help. And the new shift strategy will be night and day better.
