No problems..Took about 2 trys to get it rite....TCS one we work it over with about 700hp in a 3100lbs Door car.
Continental we worked it over with about 880hp in a 3400lbs Door car. Took about 4 trys to get rite..
But after that... Good to go...
So did it not perform as they thought? Is it common to go back with a converter for adjustments with higher HP applications? Any of yours running boost?
