I just got my smc500 and i think that the instruction booklet is missing a page because it says NOTHING about tuning. I just wanted to know how you get the percentage of correction needed for each application. Do you just set it rich and lean it out unti youre satisfied? And does higher percentages mean it runs richer...like 43% is richer then 30%...or is it vice versa? Thanks

Well i think the precentage is the amount of fuel cut from the injectors so im pretty sure 30% would be richer than 43%. Yea you should start rich but i really wouldn't recommend tuning without a wideband so you know what your a/f is.

Aight thanks...any tips or suggestions on tuning this thing? Also...any tips on enlarging the grommits for my injectors? Ive got rc440's and they dont fit in the stock injectors gromits. Thanks
