Randy drove in from Kentucky with his newly purchased V-Sport. We installed our intercooler fill/bleed kit and colder spark plugs. Running a competitor’s tune the car put down 350 whp and 376 wtq with a roller coaster air/fuel curve. We performed our custom dyno tuning and the same car, with the same mods left our place with 422 whp and 414 wtq. The gains were close to 100 whp in some parts of the powerband!
