i have a 625 mxs i backed the intake accuators all th way off it seems to run better smoother and dosent run as hot i thought about doing this a few years ago but let everybody talk me out of it , telling me that the computer would flash a code but it hasn't yet guy at the local delarship told me he had been experimenting with this and so far all is good , it has to help take some pressure off of the jake heads and rockershaft bolts nothing else ,,,,,,,,,,,,,,,,,,,,,should be similar to welding EGR valve shut on cummins .................................................has anybody tried this hope this helps some of you ACERT drivers

It should throw a code for Actuator #1,2,3,4,5,6 not responding, but I think if all of them are backed all the way off the ECM doesn't have a reference point to the pressure spike from the intake rocker hitting the actuator. I'm curious to find out if it doesn't throw a code. Keep us updated

To start with i adjusted them loose .030 instead of .020 after fresh overhaul put 10,000 miles on it ran perfect no codes no problem it only opens intake valve .004 from what I understand anyway , couldnt tell about th power difference because it was in need of overhaul so bad it had rings broke on 2 cylinders (lots of blowby) cam down, But it runs right now it's hitting a mean lick
i haul 110,000 to 130,000 4.5mpg im gona run it with them backed all th way off and let ya know how it does
