Hopefully you're running up above 1500 on a pull so you should have no fears of letting the jakes run in the same rpm range. If 18 psi is all you're getting out of it it is definitely low. Run the insite on/off test and look for full operating range of the actuator and check for air leaks in the actuator air supply. You still haven't mentioned what the psi is under a hard pull.

Read this http://rawze.com/forums/showthread.php?t...3#pid13433 for a bit of insight on the operating range we prefer and an isx should be used in.

It wants to go over 20 but I just don't let it because I thought 20 was a high. I have heard people talk about dropping valves so I was playing it safe. I truly trust the build, I was there and saw Alison's attention to detail. Plus everything from the head up is new except the injectors and they tested good. I have been around trucks and shops most of my life, I really liked Jerry's crew. They worked together good and do it right and they truly care and it shows. As far as keeping the RPMS up, I do. It's tough sometimes since I have the Ultrashift transmission but I like it because my left knee is messed up. I keep the RPMs up climbing hills by slowly down.
