Power programmers
I bought an 05 Diesel X and am wondering if anyone else had ever used a power programmer on there X.
I bought two of them to see how they work.
The programmers I bought were the Diablo hand held tuner and the Hypertech.
The Hypertech is awesome mileage is up to about 24-28 MPG and the power is great. The diablo just does not compare to the Hypertech-
Do any of you guys have these programmers and do you have problems with
reliabilty and overall comments.
Thanks combanx
