i love my trinity. get all the benefits of a tuner, plus having a monitor. id def buy it again if i was looking for a tuner for a vehicle. the best part is, if you ever sell your jeep it works for many other vehicles. so chances are you could use it again.
I saw that Bwoody(JG Vendor) has the Trinity T-1000 for $549. I recently bought the U7137 Predator. There are so many more things you can do with the Trinity though. I love the virtual drag tree feature(0-60 and 1/4 mile times)
