[4.8Silv4x4]

Just curious if most of the tuning is done through the trans if it would be worth it to buy a programmer for my truck or if i should spend the money elsewhere.

 

[bigblue4x4]

regear to at least 4.88's
I'm happy with my stock tune and 4.10's,I would be happier with 4.88's or 5.13's

 

[Hit Man X]

Tune it and regear

with 38s on 20s, skip the 4.88s, and go directly to 5.13s
