I ran one on my 383 Dart racecar. Easy to tune but not much to tune with. I ran mid 12's with it but couldn't seem to get any quicker until I changed it out for a 750 Holley. I gained 3 tenths immediately with NO tuning! Got into the high 11's tuning it before I sold the car. I will never use one again... tsk

The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.
