My comment about your convertor isnt so much about the dyno results as your quarter mile times.Assuming your hooking something is a bit out of whack,you should run in the lower 13s to high 12s with the mph posted,one of my cars ran 12.90s all day at 103.Ive found that tci,b&m ect. are not very consistent in terms of overall quality to say the least,you may have a good one but its rare.Overall even with the engine in its current form you could run faster with the car but I would also say the engine currently isnt a true 375 h.p. based on your mph either.
