Converter brand, cost$$$$ and how close was req. stall
Dynamic cost me $600.
They told me it was gonna flash at 3800 and cruise the street like a stock converter and it did just that first time around.
Infact my car sold 3 converters for dynamic. Friends that drove my car before and after the converter couldn't believe that's the only thing I did to the car. Lol. They ordered theirs shortly after
