I HIGHLY reccomend the apex TT for 3 reasons:

1) space is a serious premium, i'm finding, on our cars when you start doing turbo upgrades (as i'm preparing for). I'm having a hard time finding places to put things like an AFC, save for the glove box, and I use my glove box! The APex TT is very small and can be put in 100000 places...mine's above the air controls right now with the wire running under to thetop of the stereo..

2) Working wiht reason #1, having the o2 sensor voltage on one guage is huge, and although the guage is cheap to make, its a helluva lot cheaper just ot have on the TT.

3) I've done the factory security system mod on the apex TT, so if you want to do it I can walk you through it quite easily using vfaq.com as a basis.

What it all comes down to really, though, is your personal preference. Good luck!
