Selling Brand New OEM AC Delco LS3 90mm throttle bodies that have been hard ported with a super spiral burr and finished in 80 grit followed by a light cross buff

No tune needed. BUT a throttle body relearn is highly recommended, as with every TB install

What a ported TB will do:

Removal of the dreaded off-idle flat spot (very noticeable in manual trans cars and still present in automatics as well)

Much more throttle response at every throttle position but notably better in the lower throttle where you spend most of your time driving and say when you're doing a dig or 60 roll.

The throttle is much more linear now and more intuitive.....tip in throttle as you roll into it is also much sharper with this mod which as mentioned helps with roll racing

Increased HP and increased TQ across the board (gains will vary based on the rest of the combination but they can be significant) especially with F.I applications

Will fit the following vehicles

-2010-2015 Camaro SS

-2014-2015 Camaro Z28

-2011-2017 Caprice PPV

-2009-2013 Corvette Base/GS/Z06 (late 2009 gold blade only)

-2009-2015 CTS-V or ZR-1 looking to upgrade to a 90mm from the traditional 87mm Goldblade

Some people have also substituted Goldblade TB's on older GTO's and corvettes which use the Silverblades TB
