Maybe, I actually did the swap when I buggered up the AIS on my 2.5 TB. I was doing my tranny swap to the ax-15 and it would start because it had sat so long with a filthy TB and had gummed up the AIS. When I tried to take it off and clean it I messed it up. So I just went and got a whole throttle body sensors and all out of a wrecking yard. Left everything on it (it was way clean already) so I just put it in and it has been my best performance mod so far. I am anxious to add the TB spacer and see how much more that helps though.
