Trying to search for the post where you can fix the rev problem when you hit the accelerator it will come back to idle faster. Anyone know what to type to search it and how to do it? Something to do with drilling a copper tube or something like that?
I did it, I liked it a lot at first but have since took it out. All it is is a 1/2" copper pipe plug drilled to 5/16 in the middle, then stick it in that black hose between the idle air control and that little black box. The reason I took it out is because I found that driving it cold the morning it surged a lot. Maybe Ill go back and re-drill it out a little bigger.
If you are planning on getting a chip or reflash or maybe getting one of those SCT handheld tuners, you can have your chip/flash man adjust the 'dashpot'. That is the variable that controls how quickly the revs come down. The factory setting is slow because less dashpot can affect (worsen) emissions.
