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!!!
Power gains from this mod may not be huge but what is instantly noticable is the throttle respsonse and therefore improved drivability…… I believe throttle response is right up there in importance with power, they go hand in hand.
I was instantly impressed with the mod and would recommend it to anyone (if interested in one of these you can contact me and i can make arrangements with John to have one made for you - he does them on an exchange basis, ie. you provide him with your TB and he should have one all ready to go from the last person)
