Hi there,

I heard about this forum over on F150online (username: 05bltfrdtough) from several people but mainly JackandJanet. I have trolled around for awhile and will be receiving my CTS later this week and cant wait.

Truck info:
2008 F150 FX4 5.4l Crew
2.5 level
275/65r20 BFG T/A KO
Magnaflow DI/DO Internal Xpipe Muffler
Color matched line-x in bed and rocker panels

Some questions I have after searching around are:

It seems as if a lot of people daily drive in tow tune....am I seeing this right and if so why is this?

Also what is the equation for the tire size change? I have seen this done for many but what is the blank equation?

I look forward to this forum.

Thank you
