Has anyone have an aftermarket throttle body in there V6? Where do you get them? How much? What power gain? Or are you better off getting original throttle bodies bored out? appreciate feedback - cheers.
Have one in mine.
Better response defiantly, not sure about economy difference. You use less throttle to get going under normal driving conditions , but sucks through more air at full throttle. The ecotecs use MAF so i guess more air through it = more fuel, under full throttle circumstances anyway.
Don't know if it has anymore power, but if it is more responsive, it will fool you into believing you have more power.
I reckon it feels better to drive compared to the standard one, but mine is a manual so you get a lot more feel of the power compared to an auto.
I think the largest you can get is 69mm, unless you know someone who can modify one larger than that.
