Hi all, trying to find reviewes on the pdi big boss tuner, i was camping this weekend and my neighbour swore by it on his last coach. I am driving a 2018 Tiffin Allegro Red with 360hp Cummins,  i was told you can get it up to the 414hp and an additional 15% of torque.

Was wondering if anyone has it and their feedback please.

Also, has anyone installed the super steer motion valves? Good? Bad?
 
You might back up a bit and first ask what problems you have that needs fixing.  Is the coach underpowered?  If you get that extra horsepower, is it available at an rpm that is useful in normal driving?  Is the air suspension swaying or tilting in normal driving? Or just certain circumstances? Fixes for problems you don't have are just wasted money.
 
I put the Super Steer Motion Control valves on our Mandalay, which is built on the Freightliner XC chassis. They helped tremendously with rocking when crossing bumps at an angle.
