Im in the same boat i took my car to get dyno tuned twice and thinking about getting the pms, whatd i need to do to remove the diablo chip and hook up the pms?Also do i need to get a wideband o2 sensor gauge or can i read all that off the pms? How do i tune for boost when the car needs to be in drive under a load to have the supercharger make boost?

you need a wide band to do any tuning.

if you buy the pms new from rick anderson, he will give you a base tune to get you started which is really damn close. the safest way is to take the sc belt off and tune the motor n/a. after that is done, put the sc belt back on and then make changes in the boost table that will compensate when boost hits

this may be a stupid question but when you take your eecIV car to a tuner what software are they using?

Ok, so if I buy the tweecer, or PMS, i would still have to buy a wideband setup to use it right? And how HP for HP, how close could i get it to a professional tune?

Yes, you'll still need a wideband. You can tune Closed Loop with your narrowbands for normal driving conditions. But when you hit WOT and go Open Loop the stock O2 sensors get ignored so you need a wideband.

As far as how close you can get to a professional tune, you can actually get more. To explain it a bit more, the pro tuners do a great job. But in reality they aren't going to spend hour upon hour to get it perfect or just right. They have other cars to tune and other jobs to do. You are probably paying a set dollar amount for the tune. So if you're spending $400 on a tune, don't expect them to spend 6 hours trying to get it right. They'll do a good job (usually, if they're not doing a hack job or taking shortcuts... like just resetting the CID scalar.) but they probably won't spend as much time perfecting it as you would on your own. And to be realistic, you can't expect them to.

So if you know what you're doing, then you can get a better tune than the tuners can give you. That's basically because you have all the time in the world to tweak any little thing you dislike.

ok lets just say i bought one of these tuners, tweecer or PMS. are you guys able to give sort of an initial walk through that way i wont F up the motor? it'll most likely be in the november if i bought one.

and i already have a laptop capable of running this type of software

Ironically, that's almost my exact setup. I've got the Tweecer RT. And I just purchased the wideband controller from PLX devices this weekend (waiting for it to arrive.) Only difference is that I don't have the gauge. I'm just going to hook it up through the tweecer for datalogging.

So you should be golden with that setup.

so i'm assuming you are getting something like this

also would you be able to help me work my way around on the system if i get it. this seems really unique and something of worth to me. i'm all about doing it myself and saving some money.
