I too came from the Taco world last year and you can not compare the Taco V6 to the LC V8. Good grief not even close. So. Much. Power. And in your case you had a 3rd gen. Those rigs are notorious for being underpowered. If re-geared to 5.29's then they act right. Sad but true. On my LC I am running 285/75/17 with a lift and fully loaded going through the Colorado mountains the LC will go as fast as you want it to up the mountains. Gas mileage hurts but that is why I have a daily driver. FWIW with the lift, 285/75/17, and a Toytec alignment there is no rub on the KDSS for my LC.
Seriously though welcome to the LC club, it's a whole new world. Pic of my Taco during sale for reference.
