Massachusettes Inspection
If I were to do all the possible bolt ons to an 03 coupe and have a custom Predator tune made, would I be able to load the stock tune back into the ECM before inspection and still pass? Here in Mass they hook their computer right up to the OBDII and if there is anything different then stock it will not pass.
Also, is a Predator a good enough tuner (with a custom dyno tune loaded onto it) to use with the installation of heads/cam, or a blower? And if it is would I still be able to pass the OBDII inspection?

Not sure where you are in Mass, but I wouldn't bother with the Predator myself. There is a tuner in Seekonk (goes by Slowhawk) who can do a custom tune and you will pass inspection as well. The OBD II scan is looking for "system ready" messages as well as errors, so as long as you are clean there shouldn't be a problem. From what he has told me, he has done a lot of cars with Predator tunes and found that they have cost power.

When you put it back to the stock tune the computer will not be "ready" for the OBD test. Remove the tune at least 2 weeks before you go. Also do not clear any codes in that 2 week time, it will also show not ready and you will fail. It has happen to a few buddies of mine and I followed above and have had no problem
A lot of stations only look for the check engine light, and if they do not see one they just pass the car.
2006 = emissions/safty for odd year cars and just safty for even year cars. If I recall.
Good luck

I am in Rhody. He does a lot of cars that go through inspection, I would give him a call and speak to him directly. He is located at DEZ Racing, across from Seekonk Speedway. His name is Don. I really don't think it will be an issue, especially since big cam/heads cars are getting through but you should really speak with him. He lives in Mass and his car is by no means stock.

All they check for is emission codes...that's it! They can't see if you have a custom tune. That is simply ridiculous, without a labtop it's impossible. Do you actually think they go in and look at air/fuel ratio, rev limiter, sensor diagnostics? They look for a history of trouble/emission codes. They can't/don't look at anything else. They wouldn't even know what they are looking at? You would need LS1 edit to see that kind of stuff, so they would need a sofware edit for every kind of car made...NO.
The only reason they don't just look at your check engine light is because some people may disconect the bulb or pull the fuse associate with it. Also, they want to see the history of trouble codes. Some codes may go away, but will leave a history

If you have codes, you have a legitimate problem that needs to be fixed.
Theoretically, with the right tune, you could run almost ANY motor combo through inspection as long as you can pass the visual. If the rear 02 sensors are disabled, they will not produce emission codes, thus you pass.

The edit must be done correctly, and Don can do that. He is probably the best LS1 tuner in MA, at least that I know of and people come from NJ, PA and MD to have him tune their cars.

Miles has nothing to do with it, it is engine cycles
