Don't mess with 'em. IMHO I did tons of mod to my Chevy (I know, we aren't talking 'bout Chevys) and I regreted it. I had overheating problems and the A/C didn't work worth a crap either. Plus, if you were in traffic, forget it. The temp would creeep about 220F very quickly. The condensor for the A/C needs a lot of air for it to work right and the A/C in the Tundra just barely makes it in my opinion.
Fan drag or not, we still have more than enough power under the hood. I say, if it aint' broke.....
