should have 4.10s perfect gear for that truck.read my sig.exact same truck running 15 seconds in the 1/4
a chip is the better way to go.ill recomend tony wildman programs.but the 99-03s respond much better to programmers and pcm reflashes.
I thought I had a sterling 10.25 and not a 70...... is that not the case.
I think I was wrong about the gears unless the speedo is wrong.
LT235/85/16 @55mph turning 1900ish rpm with e4od (.71 od) I came up with 4.56
Now i have heard differently. Everyone I talked to said get a chip since they are more customizable. Im stuck between TW's chip or DP's chip. I've heard more people say go for the DP chip.
some quick calculations show that maybe if it has 4.10 then the speedometer is 10% off. Now I am going to have to put my GPS in it
Really like the center consol
originally had 215/85/16. axle code is 45.
the difference from 215/85/16 and 235/85/16 is 5%......... I am just going to use my GPS
