Hi, I'm considering installing 488 gears on my 2011 Tundra 4x4. I've had some modifications: 6" lift (Pro Comp), 35" tires... These modifications have caused a loss of about 5mpg, which I was pre-warned about. I've seen conflicting info, on whether or not changing the gears will help my fuel consumption or not. I'm also wondering if there are any other issues with this change? One post I saw earlier said something about many lights on the dash coming on after the gear change. I would appreciate any help. Thanks!
