Convert to replaceable idle air bleeds?

I don't think I have that level of drilling/machining skill...

I'm thinking of just buying a billet primary metering block and tuning the idle, cruise and moderate acceleration... then get a secondary block later (Proform catalog says their block will bolt on to a 2-corner body, although the idle screws won't work). Your thoughts?


If you are going to do that, you might as well buy two blocks and buy a billet base plate while your at it. Get it tuned up and save your money and when you feel the time is right, you can buy a ProForm main body.
