80mm Throttle body

[droppedHoe]

i have a 2002 tahoe ls and im ready to start getting some more performance out of it.
all i have currently is a spectra cai but i want to add a 80mm tb IF its gonna make that much of a difference, a flowmaster 40 series probably and a bbtune.

i see huge differences in TB prices though and i was wondering if this TB was a pos or worth buying...

what else besides gears should i look at to get better performance out of my tahoe

That Tb wont fit anything chevy....Id ask them to get you a real photo of it first..

What are you wanting out of it??To move better off the line or move out while rolling??

The stock TB on your tahoe is 78mm, that 80mm will not make much if any bit of a difference.

Long Tube Headers (LT), Free flow cats, Beef up Your Tranny, Lower gears, get the 4.8L heads and have them ported and polished, a Tune, remove the rubber crap from behing your passanger side headlight and parking light, Tune up, New Plugs wires and coil packs. the list can go on.

Stock cats are high flow cats...

why the 4.8 heads?
i've been thinking about swapping to a 6.0

the 4.8L heads are smaller and flow better.

80mm is still 80mm, not much of a difference from 78mm.
