Quote: The new XFI has a function for boost by MPH and you can set your curve to whatever you want and I have done this on lots of street cars and it works great. and you can set the traction control very aggressive for tire spin. Just a thought.
Most EMS systems have a VSS based boost control. But I've found that people who strike the right balance between it and the TCS are few and far between. If it's on your drivewheels or off the tailshaft you better have perfect traction, otherwise your boost is raising as it sees the higher VSS signal due to the wheelspin.
