[QUOTE="lincolnlocker, post: 1560314, member: 944"] Is it chirping surge or just all out screaming? Definitely cap the red line and let it open on spring pressure. What are your boost numbers? Stock 38r compressor wheel or 11 blade wicked wheel? Towed 12k all over the country with my old dually. Just click OD off at base of the hills and let her eat with the cruise set. Rpm = air flow. Lower egts. Dont think i have ever seen it drop below the speed limits on any grade and i never took her out of the hottest tune it had. [/QUOTE]
