IA 3+ for the 200q20v - commentsgreenspun.com : LUSENET : Chip upgrades for Motronic 20-valve 5-cylinders : One Thread
I used the IA Stage 3+ ECU upgrade on my 200q20v for a couple weeks. This mod uses a 2.5 bar pressure transducer, and goes up to 1.4 bar boost. Upper rev ranges it lowers the boost to save the turbo. Agressive setup, about as far as you can push the stock K24 turbo without overspinning it.
