all parts sold. thanks.

 

what size is a stock on an lq4?

 

great deal!!! i spent that much on my tac module alone from GM.

 

78mm..

 

PM sent man

 

thanks. been wondering

 

99-07 classic is 78mm i think
07-09 NNBS is 87mm will fit a 90mm
TBSS is 90mm
my truck has a p&p tb but its not perfect so id like to upgrade to this TB unless that harness isnt made for my truck

 

So with the TAC Module and conversion harness, would you not need the Dr. X harness?

 

This is correct, this is what everyone did before the Dr X thing came out but it was alot more expensive due to the price of the TAC module. But at this price is not a more expensive option and cheaper than going the Dr X + 90mm throttle body option.

 

Can you confirm that it'll work on a '06 Silverado harness?

Thanks,
Jake
