Just curious. Did you slot the holes so you could turn the TPS to get the voltage you need? If so, then that may be all you can do with it. The alternative is to put something in the intake tract to block off some of the air getting thru the air filter. That worked on my car until I got the proper parts in. All I did was take a small piece of cardboard and positioned it in there to block flow. Worked great. Hey, did it make a difference in how it sounds?? Mine did! Oh yea!
