There is your problem right there. The canned Pro-Cal tune will not compensate for that TB. You need a tune and the tuner must know its an aftermarket TB especially if it's one of those ginormous FRPP units, a smaller GT-500 not so much. The larger TB's have different "gearing" so the tooth ratio is off so your not getting the actual reading to actual opening amount read by the computer.
