I just got up, so I read it twice and still might have missed it..... But how did you measure "lacking off the line" ? An ET slip 60 ft time? Expectations - 2 inch wheelie?? None of us know if the tune is right or not because we have nothing to go off of except your expectations. Need to know how you specifically measured the cars success against your expectations. In other words, if you are thinking 1.5 60 ft times and the car cut a 1.92 60 ft time, I'd say the car is running pretty good and your expectation is way too high.
