Spoken for truth !!! I DO NOT ADVOCATE using a 'licensed copy' of any part on our trucks !!! PERIOD !!!

P.s,
geezer101, I figured out how the 'licensed copy' 32/36Dxxx variant was applied across 2.0L-2.5L(domestic)platforms which have 223-270 CFM flow
rate variance--- the 'economizer' (lol) secondary venturi --- restricts air flow between 28-46 CFM, but theoretically is supposed to increase
atomization. (burp).
Problem is, Weber (the real deal), allows venturi replacement & the there are many options... 'licensed copies' do not !!!
