Interesting this should be brought up...I just made this switch a few weeks ago.
Based on my calculations, 33" tires with 4:88 gears you are approx 17% under stock. By moving up to 35" tires, you are about 2% over stock. This is based off the stock 4runner, which came with 29" tires and 4:10 gears.
OK, enough tech-weenie stuff.
Seat of the pants dyno: There is minimal change. I noticed just a little earlier shift from 5th to 4th, and I've noted my crawl is just a tad faster. Overall, I'm very pleased with the switch, and glad I did it. I think you'll be happy with it also.
