How many MM is the TB and intake on a 5.3? Is there an advantage or disadvantage to the electronic TB?
Thanks
Ryan

 

78mm

and ETC is a pain in the ***, 06's have TM built into the damn TB

 

i thought some of the dbw was 90 mm?

 

on the NNBS, ive heard they are

 

What do you mean by DBW and NNBS? What is the TM that is built into the 06's?
Thanks
Ryan

 

DBW is "Drive By Wire" or ETC
NNBS is the slang affectionatley given to GMT-900 trucks

and the 06 Tac Module has a ramp rate built in to it that prevents the TB from snapping open. Basically if you floor it, the TB opens to something like 30% and then ramps in to 100% over like 3 seconds

 

What are the chances of my L33 having the 90MM? I called the dealer with the VIN and they were no help.

 

from the factory, no chance if its a 06-older

 

if you are thinking about a bigger TB, don't waste your money...............

 

not exactly, but here's what you're talkin about.
It's all fixed in a tune
