I can confirm that oblark has perfected his mapping, he provided me with one of his mapped ECU's I requested a conservative and safe map, my 96 850 T5 has 136k miles just been fully serviced and ITG panel filter and Powerflow Stainless cat back exhaust, here are my findings after 200 miles with it fitted:
Oblark put together a map which increases boost to 15 psi (from standard 9.6psi), the speed limiter stays at 160mph and boost limiter is 15psi... the car is considerably faster, and possibly smoother, which is a surprise. It is still very progressive with not too many traction control problems. It really flies on boost!
The boost guage now goes to 90% max where as it was about 65%, engine was a little lumpy until it learnt, the lamba light also flashed on a few times in the first 20 odd miles but haven't seen it since.
Nice to hear a bit more turbo whistle and it's certainly come alive.
