No - that's not correct. It sounds like you're putting meanings into the tables that may or may not be there, based on what the label says. In this case, it might be helpful to know exactly how the...

Re: pe vs rpm question

If you're using the stock ecm (730/$8D) then this table doesn't work the way you think it does. AFR's do not go in this table. The ecm uses both the PE vs. RPM and PE vs. Coolant tables to...

Re: Anyone with Mufflex 4in Exaust?Thoughts?

FWIW, when you do the math and calculate the "cross-sectional area," the single 4" is about 12.6 sq in. and dual 3" is about 14.1. Not as big a difference as I thought it would be.
