[QUOTE="powerstroked08, post: 902694, member: 8135"] I haven't tried that, but if you set your desired bp for that rpm the vgt is going to adjust the vanes within its set parameters(max,min duty cycle) to achieve that number. Now if the bp is going higher than the desired number the vanes will continue to open up until they get to the minimum duty cycle set limit(h&s tunes are 7% I think) Now if you turn off the vgt the vanes will be all the way open to my understanding, but you will have a laggy truck. Now thats not a huge deal but you can just set your minimum duty cycle to 1-2% instead, and set your desired ebp to say 60(at high rpms)and keep your quick spooling characteristics and have the same open vanes in the high rpms to keep your ebp as low as if you had the vgt off. Does this make any sence? [/QUOTE]
