The bypass has only been on 5-6 days I can just plug the holes. I am not running any higher pressure fuel at the moment. A mod I have been thinking about but not ready to get into.

About 100 years ago (around 2001) Mychailo did some testing with an actual WIDEBAND! And found out that the A/F ratios were very lean at idle and very rich at high RPM.
I was already running a higher pressure fuel pressure ratio regulator from an 2000 Legacy, (43.5 as I remember, compared to our stock 36.3 psi) and I "felt/tested" some improvement in accelleration!
He, Mychailo came up with the bypass mod which worked in conjunction with the higher PSI FPR to make a flatter, better A/F ratio for more better power.
This mod is probably better for the SVX people who cannot just buy a chip that adjusts the timing for evan better results!
