AEM, Dynojet, Autometer, Innovate, Dynotune. You can get one from $250-$350 it just depends on what features you want.

PLX Devices

They make a lot of different products. They are popular in the 300ZX and 350Z arenas. If I were to get a wideband Id get on of theirs, AEM or Innovative.

If you have a turbo you will want:

Boost, EGT, oil pressure, water temp

If you are supercharged you will want:

Water temp, oil pressure, EGT, boost if you have extra $.

Wideband is fine for both, but EGT is going to be more important, especially in a turbo car.

If you have a scangauge, I would not waste the cash on a wideband. The scangauge should be able to monitor fuel pressure, which will give you a window into the fueling system. Between fuel pressure and EGT you will be able to tell if you have a fueling problem. EGT is more critical to the health of the engine, especially with a turbo.

If you are doing your own tuning however, then you will definately want a wideband.

i really hate to drill a new hole on my header if i can locate it on the pipe

It needs to be before any cats, and clocked above 9 and 3 on the pipe to avoid sensor damage.

I would not got higher than 12:1. Mid 11s would be a very safe compromise.

I run my Cobra at 11.3 to one to keep EGTs down on the track.

He said it dips to low/mid 11s after that though, which is fine. A second or 2 of 13:1 under boost after throttle tip in is not going to hurt anything.

well now that thats been all cleared up. does the blitz supercharger have an electronic clutch? i was reviewing the installation manual and the wiring diagram and it had this thing for an electronic clutch and i'm assuming thats apart of the S/C bcuz our car sure as hell doesnt have an electronic clutch
