:U:

Is the COV serviceable/repairable?

how can you modify your duramax cp3 with rectangular ports?

Got an 04.5 Cummins. How does this mod compare to ordering the cp3 stage 1 "bag of parts"? It claims to flow 15% better. Will this? Thanks

u still modify the same area as you with with a regulator with triangular ports. the base

so kind of right across the middle?

no not the middle the bottom of the rectangle needs to be cut, just like the base of the triangle imagine the rectangle being a triangle for a sec, i know theres pic of a modded one with rectangular ports on the webs somewhere.

hmm alright I gotta see a picture to understand I guess.
