Your car will run 14.7:1 stoich during non-wot no matter what. Unless you fool with the PCM.
During WOT, the mixture has to be enriched, down to around 12.7:1 - 13.0:1

Re: About the ATI supercharger!!! (Cartier1)
You really need to put your car on a dyno that has wideband O2 capability and get a true reading of what the AF ratio is at WOT. Betting your motor on an Autometer AF gauge is not a good idea. FYI, FWIW I have the Autometer Carbon Series AF gauge, I am running the 7 PSI pulley, and when I go to WOT, the lights go to near or full rich (near the last or the last green). If you don't have access to a wideband O2 dyno, at least AutoTap the car and monitor the O2 voltage readings at WOT (0.88 - 0.89 volts).

Those octane boosters are hard on your motor and emmisions systems.If your going to run 1 the one you want is Turbo 108 it claims 7 Oct. Pts. but is good for a full 4-4.25 per 20 gallon tank 2/3 of a bottle tops per tank.We carry it as a local item along with 109 race Gas but if you contact Shawn at LAPD and tell him I sent you he will cut you a good deal,stuffs not cheap but works better and cheaper than Amsoil which is made for a 12 gal. tank.
