thast waht im plannin on using. thanksnot mine. iv got some weird idle issues but i dont have any problem pullin 75-80 down the freeway with 35s and 4,37s on all but the steepest of hills. 
the biggest thing that helped my V6 out was ditchin the IFS. It weighs like 3x as much as a solid axle does and i had auto hubs and my vacuum thing was broken so it was always spiinin all my running gear. I noticed a huge power increase when i switched from IFS and 30" tires to a soild axle and 35" tires.
try goin from auto to 5spd... then IFS to SA!
its like letting a lion out of the cage... and I also have a HEAVY ass 4Runner too.
