Nah, keep the 4.10 until you are running out of rpm at the finish line.

 

i run 4.10´s in my turbo truck and it works great, why did i always hear that once i had a turbo i wanted a lower gear, u guys are saying the opposite, i'm confused

 

^ this exactly, if you're using the gear. Unless you are revving over the power curve of your combo.

 

6s easy if you let me give you some advice and tuning help

 

Higher gears (numerically lower) will make boost more easily (relative to RPM), but be slower. Lower gears (higher numerically) will not make boost as easily (relative to RPM), but you will be faster. A lot of guys confuse a number they see on the boost gauge for how fast they are. So do you want to make boost or do you want to go fast?

Keep what you have.

 

Been battling with guys for years; over this.
Gearing is a wonderful thing.
Especially if you are not worried about gas mileage at 75mph.

Mine is getting 4.10's.
