2008 GMC Throttle Bodies

[TexasGMC]

BBK Performance Parts will not be making a throttle body 5.3 GMC or Chevy's.
for 2 reasons.
1- The stock throttle body is huge and no power gains would be found by increasing the size beyond that.
2- The eletronics in the stock TB cannot be swapped over to another unit.
basically if the were to make that it would be about $750.00 for something that shows no increase in power! So it hit me I asked about port and polish and Bryan Rogers of BBK said "Don't touch the stock TB! doing so would just open the door to problems and expense with NO gains on power!

Yeah, I would not expect the see gains on a stock 5.3, but as you mod these motors, there is no question that larger TBs are worth some solid power.
