I did it just for fun, but don't have the results handy. I used a rich mixture, like 12 to one, and used a brake specific fuel consumption of 0.60, as I remember. That got me about 300 hp from the 255 gps which is the max that the stock MAF will read. It also matched up pretty close with the capacity of the stock injectors. Obviously, you can get more power than that, by running leaner, using higher pressure to the injectors, etc. Probably somebody has this on a spread sheet.
