I went ahead and bought the Bullydog Power Pup. I received it about 2 weeks ago, so had plenty of time to see if I felt a difference with it on my vehicle. I have an 07 3.5 SE CVT with AEM CAI and Stillen catback exhaust. When I received the power pup I hooked it up to the computer and updated it right away. I plugged it in the car and it went through its process, then it told me it needed an update again. I called Bullydog and they had a new update available, so I installed and plugged the unit back in the car. It took about 25-30 minutes to install, I set it at premium tune and left the rev limiter and speed limiter stock. After driving the car for 2 weeks I don't really feel any increase in power and it hasn't improved my fuel economy. I did notice it made the idle a little higher on premium tune, but like I said no power difference to me. Another problem with the unit I'm having is I can't adjust timing or idle and Bullydog claims these are both adjustable. When I called them about the issue they informed me to call back in a week, they would have their engineer get a car like mine and mess with it to see what's going on. They informed me there would be no guarantee they could fix the problem, but they didn't want me to take that statement the wrong way, WTF! So I got a product that doesn't do all the things that they claim it does and they won't promise it will be fixed. I already setup an RMA to send this unit back, I'm within my 30 day return window so all i have to pay is return shipping. I really can't recommend this unit, maybe it works wonders on the Nissan Titan but not on the Altima.
