I’m putting together a spreadsheet for everyone on the CAI for the FJ. I just bought the Scan Gauge II. I plan on installing the SG, then monitor existing stock performance using Fuel Rate, Manifold Pressure, Tachometer, Intake Air Temp. Then I’m going to buy the TRD CAI and use the same type of performance data. I’m going to use the same gas station, Mobile One fuel, run the test with different types of Octane, same mileage, same speed, etc. I’m going to try to make the testing as clinical as possible. I will be documenting the figures into a spreadsheet. I will then post my results. I do have the TRD exhaust though, it came with the TRD; everything else is stock. If anyone wants me to monitor certain information, let me know. Would anyone be interested in this information? I looked around on the forum, but I found what is provided by the Mfg. Is it just me that is interested in this data?
