Ifr Spread Sheets Hi, can anyone point me to an ifr spreadsheet that works for a factory supercharged car like the cobalt? my ifr table shows negative kpa numbers as well as the normal 0 to 80 kpa. i've searched the forums and can't find one.

If your old IFR table is linear, the new one should be linear. I'd suggest using the IFR sheet in the stickies for the 80-0kPa of manifold vacuum and use a little algebra to figure out the rest of the numbers. Excel will help simplify the math a little.
