I had the converter made by Hughes . Its their 9" race piece(dam near 1K $)
They are real nice and say they will redo,free,as many time as it takes.
I think they don't have alot of experience with "big" turbo cars.
I just don't get enough seat time to give them good data ,to make changes.
I have been told FB Trans shop does a "variable" stall??Also Neal Chance has one,that is working good on another car with a combo close to mine(Jim Byrne at Precision Turbo's car)
The car has got some real nice pieces,probably high 8 second potential,but it has a mid 13second driver!
