I have a 38mm tial ordered.

 

Thanks Evil, I am trying to get around spending any more money. I am a little worried about blowing a headgasket playing with the boost on the street. As soon as the tial gets installed I'll be looking for a dyno in the Birmingham or Atlanta area.

 

Make sure you know how to tune the car before you go. That will save you some cash. Time is $$

The idea behind getting a wideband o2 is that, you can get it very close on the street (and always keep an eye on it, without going to a dyno) then fine tune it on the dyno.

 

Will do.

 

With the Tial, I'd opt for a full 3 inch exhaust and an Electronic Boost controller. The EBC maintains boost better and if you run abv 15-16 lbs, you want prcise control of boost...
My 2 cents.
