turd with a/c on

[Lola]

Under drive Crank Pulley will make a difference. Put one on my 04' and she honestly got a little more pep in her step. Better MPG also. Slows down the A/C Compressor, Alternator and Power Steering.

Back in my Racing days, my street 4.3L S-10 before I swapped in a 6.7L I had the A/C Clutch and a few other stupid things beautifully wired into a Wide Oped Throttle relay. Hit Full Throttle, Stuff turns off. It's easy if you're good with electrical.
