I have just had the stage 1 Hirsch upgrade to my 05 9.5 2.0 lpt taking it
from 150 bhp to 220 bhp. It only involved an ECU reprogram (about 40
minutes). The performance improvement is significant.
The reason that I went for Hirsch is that is fitted by Saab dealers and all
Saab warranty's remain intact. My insurance company seemed more pleased that
it was approved and fitted by a Saab dealer.
At the moment there is a special on till the end of November on 03 to 05
cars for £675 at Squires Furneaux in Dunstable or Welwyn Garden City.

I have been considering Saab's recommended Hirsch upgrade for my 93 Aero210BHP convertible. Stage one (£700+) is simply modifying the ECU softwarewith a PPC unit which only gives an extra 20BHP, stage two (£2600+)involves a new exhaust and intercooler but gives an extra 42 BHP. Swedish company BSR seem to offer a similar ECU software upgrade via their own PPC unit which they claim gives an extra 37BHP for only £500. Does anyone have any experience of either a Hirsch or BSR ECU upgrade? Thanks
