I just added the trail dash 2 to the jeep. I set up the 87 octane tune. All I can say is WOW!! It made the pedals super responsive, all sluggishness from the 35's is gone! So much so that I had to relearn my muscle memory with the use of my feet on the pedals (manual). And best of all, the increased performance has also increased the fuel efficiency. I used to use 14L/100km now I'm down to 10.6L/100km, that's 4 cylinder sedan territory!! Couldn't believe it. I also recalibrated the speedometer and tachometer for the upsize tires and deactivated the TPMS sensor.
I like seeing the MAF volume, intake temp and coolant temp, to name but a few gauges it can display. Once I switch up to a Banks CAI I will actually have numbers to compare volume and temp, thus performance.
