Anyone have a good suggestion on a tuner upgrade, I have been looking at the Bully Dog and Diablo...I am sure this has been brought up before and I do apologize if I did not look hard enough for the thread.
I don't use a tune on my Cruze, but I do use a custom tune that was done with a Diablo tuner on my 2011 Sierra, and it is really impressive as to what it did with my truck. Did not use a canned tune from the tuner. Downloaded data logs with the tuner, then had Lew with Diablewtune.com do a custom tune and downloaded it to my truck. Big difference in power and responsiveness.
