I am very, very impressed with this unit! You can data log up to 3hr on it. You can display your boost as well as your RPM on it which is great. You can go from bar, to psi, to kpa with no problems. Install was not the easiest but it was well worth it. There are so many features in that thing! YOu have 4 options of looking ath the readings. In digital, graph, bar or gauge.
ANd also you can controll your fuel and ignition timing and remove your fuel cut once you get the optional $300 fuel computer which is cheaper than the afc apexi. This is well worth it if you plan on upgrading and getting a fuel unit. If not then this might be to costly. I would go with the blitz unit instead or the greddy profect-b.
