DO NOT and I repeat DO NOT use the AEM wideband. It is a piece of shit. You will have so many problems and heart aches with it. Vijay has tuned about 5 dsm's with the AEM wideband and only one of them worked with no problems, that's not counting the other cars that have had problems with them.

If you want a good wideband/gauge go with the fjo setup. Call Geo at Titan (407)277-8423 and tell him Ian sent you and he will give you a good deal and go over the aem gauge vs the fjo setup.

For all of your other gauges I would say just go with the tried and true method of the autometer gauges. They make a boost gauge that goes up to 65lbs I think and also one that goes up to 40lbs but it is called a "blower" gauge instead of boost, same difference.

Or as boost junkie said, if money is no object go with the defi gauges. AFAIK they were what the greddy/hks gauges were originaly modeled after.
