Port and polishing a 4.7l throttle body
I have a 2006 Ram with the 4.7L.. Im wanting to port and polish my throttle body. Will this show any difference in performance or throttle responce on this engine? My friend has an 06 chevy with the 4.8L v8 and he ported and polished his tb and he said he could tell a big difference afterwards. I know one thing, he has a poweraid tb spacer and you can hear it whistling pretty loud when he leaves out down the road, so it has to be getting alot more air. i have one installed behind my tb too and the whistle is not near as loud. we both have k&n CAIs.. If you've done this before on your 4.7L let me know how it turned out and if you have pics post them so i can check em out.
