jadaven Posted September 24, 2005 Report Share Posted September 24, 2005 Looking to do some modifications to my truck. Anyone know the stock size of the throttle body on a 2000 chevy silverado 4.8 liter? BBK makes a 80mm throttle body,just wondering what all I can gain from changing it out and what I would be changing from. Thanks. Quote Link to comment Share on other sites More sharing options...

jadaven Posted September 25, 2005 Author Report Share Posted September 25, 2005 Sweet Dude, I'll be checking it out. I'm just looking to get some extra HP and MPG out of my truck. I just ordered the K&N 77 series intake and some other stuff. looking at a new MAS, and throttle body. I cant wait to see what all i can get out of the o'l beast.

04ShEeLE Posted September 27, 2005 Report Share Posted September 27, 2005 I put the Granetelli Mass Air Flow Sensor on and I didn't notice any gains on anything. I don't think it is worth the $300+. Quote Link to comment Share on other sites More sharing options...
2twin350s Posted September 28, 2005 Report Share Posted September 28, 2005 go buy a programmer for you ecm, that will get you the most gians for a cheap price. plus it will alter the shift points on the trans. i think they are like 300 bucks. trust me, i wrenched for gm for 12 years. MASTER TECH. you can do all you want to the truck, but until the ecm alters the fuel pulse timing and spark timing, all that crap wont do any thing for you but empty your wallet! as far as a bigger throttle body all that does is let more air in.it has no effect on injection pulse.
