Ok, heres what I did. The boost bypass valve I toyed around with. First I took the two screws that hold it to the supercharger loose and pushed the valve down as far as I could. Then I went and took an alen wrench and backed the middle screw out till it was flush with the holder. This seems to have increased the boost (or at least the RPM the boost kicks in) by a considerable amount. I guess my question is: is this a safe mod to do? Also those of you who put colder range spark plugs in your RL what brand and number did you use also how many heat ranges colder did you go?
