Default Tubos and Gear Ratios..Tell Me Yours!!

Guys running Turbos tell me what has been your best gear ratio, from what i understand they love taller gears so how tall are yall going?? I dont want suggestions i just wanna know what you have ran or currently running on gear ratio, im having no problem building boost with my front mount and 4.11's but i know it will make a hell of a difference if i goto a diff ratio...Thanks! Opps i made a boo boo up there (Tubos) for anyone who was gonna say something lol

Tried 4.10 and currently use 3.42. Truck blew tires off too easily with 4.10 and 3.42 made it more drivable. Best 60 ft was with 4.10s, 1.56 and so far I've had 1.61 with 3.42 but still need more testing.

On MT 315 65 15 drag radials it hooks 30mph and up on 7 psi & 16 degrees, on 10 psi it hooks 55 up and on 15 psi it hooks 70 plus. I just ordered the new 20" DR and will post rolling wot before and after if I get a camera guy.

I'm rocking 4l80 gearin, 3.73s w/ 29x11.5 hoosier QTP. Sometimes I wonder if I'd pick up going to a 28", but I spin the 29's about 20 feet out at the track sometimes. So far, running 13-14psi tire pressure seems to help. I also ordered some Rancho RS999262, I hope to get some control over the rears movement, firm it up over the ground control shocks with 92k miles on them. I currently cut 1.61-1.65's every time out.

Tarinitup, how wides your 20's? Also, I run my 305/35/20's at 22psi, daily.

Gavin why not run a 29" if your thinking of swapping gears?
