thanks after doing more research many say the nos charts are way to rich so if i use .061 n20 and .055 fuel might be just right of course with a good tuning and reading the plugs. i did a calculation i found online and with this jet combo and 6.5 psi fuel pressure and 900 psi bottle pressure it should be 142.83 extra hp to the rear wheels thanks for pointing me in the right direction.:burnout:
