Holtzman Tempa Flow, does anybody have anything to say aboiut these? So I just het rich and it leanbs it out with the air jet?

Do a search and use "Tempa Flow" for your search. I put one on my 99 ZL and love it. Tempa flow only does temperature. It runs great and I got better mileage.

That is the one, how does it work? Where do you put it?

go to their website,,,,type tempaflow in search and it will bring it up,,,, holtman engineering??? seems like a really nice piece!!!
