going from 3.73 to like 4.10 gear you will notice your fuel consumption greatly increases i never recomend gears like a 4.10 unless using the vehicle to tow a heavy trailer or extreme offroad applications or strictly drag racing
my last truck had 4.10 gears and now this tahoe i have has 3.42 gears i totally notice the difference the mileage is alot better plus driving down the highway at 75 my engine isnt tached out like my truck used to do

I run 4.10's and can drive from Houston Tx. To spearman on two full tanks and a half of fuel and I only have a 20 gallon tank, I also have a fully built 4L80 tans and a Circle D converter with a 2800-3200 stall, shift kit , and a 6.0L with a Texas speed stroker kit heads cam TBSS intake LS2 throttle body, Walbro 400LPH fuel pump.

I'm at 2200-2346 RPMs at 80+ MPH

Ok so my wife said it was the tanks not two and a half.

Well the day came and went. I had no choice but to use my 01 Denali to pull my 30ft 7900lb toyhauler over the weekend. It actually surprised me. With minor mods and a cookie cutter tune I managed to pull 209 miles on a tank of fuel and still had a little under a 1/4 tank left. My average speed on the freeway was 65mph and the truck really didnt labor at all. All I did was do a massive maintenace tune up and installed a hand held tuner I borrowed. I changed every fluid and every filter. Plus a new set of Delco plugs and wires. I'm satisfied. The Supercharger will have to wait for now.

Thanks for all your help guys. I'll tackle the supercharger in November.

I am new to this forum, but after reading your thread, you sound a lot like me. I tow a 35' TT and have three kids and two dogs so a big truck was out of the question. We had a 3/4 ton burb but it was only marginal, because it had 3.73 gears. Our solution was to swap in an 07 LBZ duramax with the Allison 6 speed and HD Truck 11.5 rearend. Ours is 4wd so the heavy duty T-case went in also. This can be done with 1/2 tons also. It is incredible what a boat load of torque will do for towing, simply said, awesome. It was way cheaper than a truck or even a used Excursion with a diesel and I got to keep my favorite Suburban. Look into it under the Frankenstein section of the Diesel Place forum.
