Question for adjusting shift points with the Predator programmer
I have recently purchased and loaded/installed the Diablo Predator and a set of gauges (pyro, boost and tranny). A local diesel mechanic suggested I adjust all of my shift points up about 200 rpm to keep the boost pressure up (in an attempt to increase fuel mileage). Is this theory true? I have read several posts about guys adjusting their shift points. Can you guys tell me why you adjusted your shift points and what you adjusted them to? The manual that came with the Predator is a little vague in covering the topic of adjusting shift points. Can I adjust shift points on all of the programs or just the high performance program? I run the economy tune primarily and run the truck around town a lot. Any input would be greatly appreciated.
