The EMS Plug right in, but you'll need to get it tuned to work well with your car.
I like what I'm hearing.

So it was stock with the exception of the Vortech and AEM EMS? Nice numbers.

I hear there are 2 different types of AEM EMS, one is UEGO and one it not. what's the difference and do they both plug in?

UEGO has the Wideband O2 built in.

Everything was stock with the exception of the Vortech Kit. I used the pulley that came with the vortech kit.

7.2 psi on a MY00 AP1

- You can buy it from almost any performance shop

- anywhere from 1200 - 1500 for the EMS

- check Church's website out for Info: http://home.earthlink.net/~spchurch/...motivetesting/

- wide band is mostly use for tuning the car properly, it shows the true air/fuel ratio.
some tuner will use their wideband (either connect to a extra o2 sensor bung or connect it from the exhaust)

it is also nice to have so you can see if your running too lean or rich.

Looks like Church charges $160 an hour to tune. so figure 2-3 hours to tune it?

Also are there any reliability issues with the AEM EMS? Any hicups that come up?

the 8 months that i used it stock, i have no issue with it what so ever. and i drive my car very hard. its my daily driven car.

couple hours should be more then enough since everything else is stock, unless you added other things.

My initial setup and tune was less than 2hrs. Subsequent re-tunes can often be completed in an hour or less.
