Spent good part of last season learnng the speed pro and getting to my base line down.. Season is short here in Western NY and no one has the sys around here. ONe problem I ended up with-- with stage brake, launch at 13# at 4000 rpm- car jumps out and immediately dives and then jumps out again. All this in a split second or two.. 72 turbo and 83 # injectors.. Base line was 11.5 fuel and 24 degrees launch & down the track timing.. Will leaning that out and moving up the timing help?? If so- to what?? LArry
