This is for a bone stock 2003 Jetta 1.8T owned by my girlfriend. I'm not going to spend the money on a chip b/c it would be a waste, so I think a solidly built manual boost controller will have to do. I've got access to a VAG tool for onboard data logging purposes. Any ones that you'd suggest? I've heard the Hallman unit is popular via the post below.

chip...a waste?

WYSIWYG

you should know better than that - air is just part of the equation

CP

Yeah yeah...I'm not spending the cash on a chip for this car.

I'd be surprised if she has ever dipped deeper than half throttle.

EDness

then just leave it alone.

Ill sell you a split second EBC for $175. It is brand new and never used. Some one gave to me as a gift but my A4 is non DBW. This EBC is $250 new.

MBC alone won't really help you. You'll quickly encounter throttle cut from overboosting if you don't clamp the MAP sensor.

If you are looking for an easy way to get more performance, go with the chip. Manual tweaking is NOT an easy thing to do on these cars (can be done, but not nearly as easy as a chip).

VW/Audi dont define the air fuel table enough to run just an MBC. You could squeeze out maybe 11psi before you head off the chart.

I hate this DBW engine. Put your foot 1/4 way down and the damn thing takes off like I had floored my old non-DBW. The rest of the car is junk anyway. Says alot for VW's Mexican build quality.
