Hey quad, i recently bought a older pressure box for a buddys 04 Cummins. It worked great when we first put it in, and good for about a week after that. Then he felt as if his clutch was slipping. He keeps it on the 50hp setting and does not Tourture the truck. The other day he was accending a hill and the truck lost all power. he didnt know why and removed the box anyway. The truck has since run like a champ.

Any ideas?

 

You should call him or email him. He is a busy guy & probably doesn't read the help section.

 

i've tried both, waiting for an email reply, and will phone again when i get home
