[QUOTE="CPRsm, post: 13640364, member: 81705"] The SW could be more restrictive? The muffler maybe? It would make sense if it was. Would explains lower spool also. Changing back pressure can screw w boost setting pretty easily. Most springs are rated based on about a 1.6 back pressure ratio. Boost will vary depending on kit design and back pressure. So a simple change in exhuast can definitely change boost settings involuntarily [/QUOTE]
