MAP2 tune on an OBD1 I have listen to some of you and realized that my car has a half-*** tune (stock motor, procharged/intercooled, 5psi, delteq, botl-ons). I've found a tuner in the Philly area that is willing to tune the ol' LT1 but was told that due to the car being OBD1, I cannot have an MAP2 or MAP3 tune. Is this true?
Also, is it possible to have multiple tunes on an OBD1 car? Say, if I wanted to play it safe on the street and roll the dice at the track.
Thanks all

You cant load more then one tune on a pcm at once. I would suggest a mild tune on one pcm and an aggressive tune on an extra.
I know you can run it as such, but how much PCM fooling is done to get the PCM to see boost?
Granted old, but everything I read says its not a simple, 2bar OS load..

I think you have to repin factory harness cause the 2bar and up sensors are different pinouts than OEM.

Ive been running 12 lbs of boost since I started back in 97 on a 2 bar map, everyone does not understand what they are doing, what they say to do with a 2 bar is really done on a 1 bar, thats where all of the calculations come in, I use to run a 1 bar with 12 lbs then switched to the 2 bar. I tried to show how I did it and everyone said I was wrong. OK, Ive been running 2 bar up to 15lbs, made 722 rwhp but yea I dont know what Im doing....

I am honestly curious if its as simple as loading a 2bar OS onto the PCM, or is it a matter of tricking tables etc to make the PCM cooperate with boost levels.
This was not directed at you, I was just stating how I did it and how long I have been running the setup.
