    Upped Boost to 8# this last outing , launches like a raped ape and did not blowout pump, Saw 6800 on tach recall limiter was set at 7200 but it laid over about 100 from line like a fuel issue , going to recheck carb bowl float levels and maybe up fuel psi a hair. Target is try and run 12-15# boost
