Ported Throttle Body

Improving throttle response without buying new parts.
A friend and fellow Commodore owner, John, who lives locally to me and is also a gun on his laptop with EFI Live (pcm tuning), has also got into porting and polishing the factory throttle bodies on the commodores.
While I had heard that upgrading the throttle body was a good mod i always believed this was more to do with buying a bigger diameter throttle body which were rather pricey, so when John got into upgrading the factory throttle bodies I wasn’t expecting much of a difference…….. how wrong I was!!!
