First off, welcome aboard.

Secondly I would look into getting a custom chip made for your car. MAP engines don't like huge changes in their parameters. I'm still running mine on the stock chip and the idle bounces around like yours does.

I have sent an e-mail to hypertech and i am awating there response hopefully they can hook me up with something cause i hate this ideling bounce as it drops so low that it could cause bottom end problems. thanx again

i donno how well the hypertec will ffit your peramiters... Id look into either burning the chip yourself ( there are board and tech articles dedicated to this here) or taking it to a knowlegable shop and having a chip burned for it.
