Whenever I encounter a problem with one of my cars, the first thing I logically do is to identify the last change I made. If it's an aftermarket item and reasonably related to the problem at hand, then that's what I have to rule out first. It's just a process of elimination that I can do before succumbing to going to the dealer.

One other thought - if the bog comes back, and Unichip allows a mechanism for you to datalog the car and send it back to the tuner for review, you should do that as the tuner should be able to identify what the issue is and if it's something that can be tweaked in the tune.

You don't have to tell me...I basically said exactly the same thing on page 1.

If the car is still cold and you have the front window defrost on (runs the AC compressor) then it could easily be bogging a tiny bit from dead stops. Really cold air is also a lot more dense and it could be running too rich.

If you're not doing anything differently (ie driving the same, heat/defrost on the same, etc) every day then I would put money on the tune running too rich with really cold IAT's.

For the record, I was never blaming the tune I was simply saying you need to rule it out because it COULD very easily cause issues especially under varying conditions. For that matter so could an intake, a bad sensor etc etc.

Process of elimination is your friend when you don't have any trouble codes to start with.

Thank you all for the support so far...I had slight hesitation one time this morning...but that was all. When weather gets better, I will try the chip. I talked to jack a few days ago and the customer service was great. I would imagine that their tunes are built with all weather elements in mind.

Another note, I will be refueling the car soon... when near empty when the time comes...will try another place. Cant hurt.
