Max Jake boost ...

[the missing link]

Alright time for my dumba$$ question. What should your max boost on a 871 be when jaking hard , high rpms . Oh and on a "fixed " 871 , hehe .
I know that they will Spike and then drop back down a bit and the higher the rpm is the higher your boost will be . But what should your max not exceed once it settles out .
I greatly appreciate all the knowledge.

~ i think mine is usually around 18 ish? -- Too much boost and you could drop a valve at higher rpm's.


-- The factory settings + correct program for your make/model truck for the engine brake should only ever be used.

This may be off track a bit but on CM2250 mine is around 32-35 psi at manifold.
