My knock problem theory. Make sense or not?

Good idea. Adding fuel should also tell me if my a/f ratios are off too i think.

Here is the mods list for the 99GSX:

PTE 50 Trim w/cut divider/Internal Gate, PTE 780 Inj, FP 3" Intake Pipe, HKS 272 cams, Griffin FMIC(24x10x2.75 core), Magnus Intake Manifold, 1g TB, 2.5" I/C Piping, DSMlink, TurboXS BOV, Hallman MBC, Rewired 255LPH F.Pump, Fidanza Flywheel, SouthBend Clutch, 3" Exhaust, Greddy A.Filter, 75/25% Alky/Water INJ, (2) 1400 cfm Fans.

Thanks... I will try it tonight.
