[QUOTE="FORZDA 1, post: 1321940, member: 26637"] I had a relevant question PMd to me asking about the jb4 tuning device and when I responded it was too many words for a PM. So, I've posted it here for that person to read. It is almost a rehash of previous posts in this thread. I just had a laugh going back and reading the dumbsh*t posts from the ignorant people on this forum. Anyway, here it is: "No, I haven't tried the jb4, but it is a piggyback/interceptor device and I have years of experience with these devices on several different applications. They are ancient rudimentary band aids for affecting individual sensors for tuning "effects". The ECU still runs it's regular programming, but you "intercept" and change (usually) the MAP sensor and the crankshaft position sensor signals to a different value, so the ECU uses that value to calculate the fuel and air required to hit the falsely requested Torque/Load.
