i just bought a pulse manifold and i was wondering if anyone else ran them and how much they helped. Oh how hard are they to put on.

 

Don't know much about them but Caterpillar is putting them on their engines now. Puttin one on is probably going to be the easy part. Getting the old one off will probably be the hard part. I used boiled water to break the studs free on the last manifold I took off. Seemed to work pretty good.
