I have used the search function and still have a couple of questions: First off, my fuel system is comprised o SFMU using 2nd to largest disc w/bleed valve),Walbro255, Hahn's in-line f/pump, RC 440 injectors, and the safcII. Also have the pocketlogger. First question is: I cannot lower stft less than -11 at idle(ltft are -25).Am correcting as much as -15% at 1000, 1600 and 2200 rpm. It has been said repeatedly NOT to use more than 5-10% correction. Will I be ok to adjust more correction to lower stft/ltft? Then finally, when using the bleed valve on the sfmu, does it alter the vacuum(un-boosted) rate-of-rise also? F/P@idle=12lb. F/P@ 15lb of boost=100lb. (Am using Hahn's stageII turbosystem.) TIA!
