If it is ok which one is the best out there for the $$? i really > like the sound of the blow off valves:) You can, but it must be a double piston type valve like the Forge Motorsports FMDV004 or Baileys DV26. Being a closed loop FI system, you will get a slight richness when the valve "blows", but it won't be noticeable in practice apart from quickly letting off the gas in higher gears; there's a slight stumbling feeling. You won't get any benefit, other than the sound ... Which might not be becoming of a lofty CD :) Paul 1989 900 Turbo S http://saab.go.dyndns.org/
