I could see and feel the the increase in power and economy within the first 100 miles. Should pay for it self in about 6 months.

Easy to use with good options. I specificaly wanted to disable the V4/V8 switching on my 2007 Tahoe. Others say they can do that but they don't. The I-1000 does and it works great. Also was nice to be able to disable the 100 MPH speed limit.
