After looking for a 5-seater SUV for about three months, bought a Jeep. Looked at the new Acura RDX (Very nice), Infiniti EX, Audi Q5 and Lexus RX350, I went for a Summit. Picked it up three days ago and hope I made the right move. The Lexus was very very nice. In any case, consider me part of the family. As we have seen, gas prices are going way up. I usually keep a vehicle for a long time. Also have a 2002 Acura CL Coupe that I bought new. Has anyone used the Gforce chip to improve mileage and performance?
