Why do you care how much boost I choose to run? If the factory didn't want them to be adjustable they wouldn't have put the "screw" on them now would they? Get over it! Jim

As I recall on my '87 Daytona Shelby Z, the factory computer limited boost output. The Shelby Z was set to 12 PSI with a peak of 14 PSI and then only for brief intervals as it was an intercooled engine. The more common Turbo I engines (non-intercooled engines) peaked, I believe, at 8 PSI and 10 PSI max for brief intervals. These "high peaks" are for "passing manuvers" and not for sustained operation. Sure there are ways to by-pass it but the factory does set limitations. Otherwise everybody would start fiddling with the adjustments and there would be warranty engine claims all day long.
