Throttle body upgrade
I have a 1998 Chevy Silverado 5.7 vortec. It has a
few mods like mpfi injectors k n cold air intake
VMAX spacer shorty headers throttle body spaces
MSD coil MSD distributor. I'm looking in to
upgrading the throttle body but I dont know how
big I got with out having go get my truck tune. If
someone can let me know what the next size of
throttle body I can get with out a tune?
You can go a little bigger but going a lot bigger won't help unless you get deeper into the engine and change the camshaft, heads, etc
Right that's next year project.. you happen to what throttle body mm I can go too?
