Default help needed! - experts only please!

OK.. this is my nightmare!!
I changed my MAP sensor twice a week now, can't figure out what is the problem(s)!
every time I hook up the diablo to see what codes I have, I get the MAP sensor.. MAP sensor.. MAP sensor.. MAP sensor.. MAP sensor..
some will say "you have a MAP problem" I ALREADY KNOW THAT THANKS A LOT! but what is causing this? is there any problem with my car/mods? - I got "Unknown" code too! what the hell is that too?
Thank you!

Then dont hook up the diablo, that could be the problem. Find a tuner who uses a real tuning program.

Sorry to be so direct, but we read alot about hand held tuners turning into major problems

Is the car stock? A larger cam can cause MAP sensor codes.

Sorry but the diablo doesn't seem to be the problem here,his MAP is the problem.I would venture to say that all those mods are causing your issues,exactly why however,I can't say.Good luck in finding the cause of the problem.

Is the Diablo programmed for the supercharger??? Who installed it anyway and do they know you're reprogramming the PCM?

I have a maggie on my 05 with a 2 Bar map sensor (non stock) with EFIlive programming. Some tuners go with a 2 or 3 bar map sensor that has different outputs and require specific programming.

I'm not sure whats going with your setup. If youv'e got a good map sensor with the right programming I'd start by checking the voltage output for the map sensor traced all the way to the PCM. It should be 0-1v. You could have a pinched wire or something?

I'm not re-programming, I am checking for trouble codes.
should I use a special MAP?
