I have agree with you… I cleaned my upper and butterfly values @ 60k, and I was in shock at the thickness of the layer of crap that was caked on. I would guess that any benefit from the extrude hone process on my SVT is totally negated within 15 thousand miles.
As far as the injector removal tool… Yep NAPA will be your best bet!
What prompted you do all this work? Are you having some performance issues, or is the butt dyno telling you your missing that extra something?
