I was wondering if anybody has a car tuned by HPTuners that has gone through MA state inspection recently. A friend of mine just brought his mustang through inspection and failed. He had a programmer that was causing the failure. He had to swap back to the stock tune to get it to pass. I have until December before I have to get my inspection, but was wondering if I will have a problem. I will definitely fail on my stock tune, so that isn't an option for me. Anybody?

What does it look for? The OBD II tests to be "ready"? That should be passable with working emissions systems and no codes disabled.
Connect the VCM scanner to your car and open DTCs. The first tab should provide the necessary information.
And how exactly did your friend put a stock tune on? via dealership or put a stock calibration on with his tuning tool.
If it was the former, that might make sense. Otherwise I'm not so sure.

No idea what it looks for. This is the Democratic Peoples Republic of Massachusetts (DPRM for short), so there are no limitations as to how far they will try to go. He did say that they told him at the first failure that two sensors were not showing up. I wasn't there, so I can't provide any further info than that. He has something like a Hypertech programmer (forgot which brand), so he reflashed it back to stock.
My car with the stock tune trips the misfire code and catalyst efficiency code due to the cam and high flow cat. I have them both set to not report and have not had a problem in the past. He has been through emissions before without a problem also, so it must be something new they look for this year.

Massachusetts Vehicle Check
Basically it needs to be able to communicate with their scan tool and all but one of your OBD tests must read ready.
Hookup your HPT and check it out to see whats going on. Then go from there.
Does not mention anything about looking for sensor data, however its possible they do. Just make sure everything on the standard OBDII list works. Things like both O2 sensors, EGR position etc.

Thank you Matt! I poked around the RMV website, but did not find that page. My understanding is that our cars show ready if the test is set to not report. I'll hook up to it and see if everything shows as ready.

they do show ready when the code is set to not report. I have gone through CT that same way in the past. I believe some of the newer vehicles don't become ready when the code is set to not report. IIRC Max had that trouble with his G8
