don't they have around 240 hp and XXX lbs/tq? and how heavy is the Tundra? i had a brief encounter with one yesterday afternoon along 19th Ave. i was surprised that a pick-up truck was able to hang with the IS from 0-60 mph. by the time we reached above 60 mph, his front bumper was somewhere next to my rear doors and i was slowly pulling away (and i mean very slowly). i had to let off the gas pedal and slowly hit my brakes when i saw my speedometer reached around 75 mph. the other driver did continue weaving in and out of the traffic though, so he could prove that his truck is superior to my IS. i don't have any modifications done to my car. i guess it's time for modifications.
