had a chat with someone at torktek and they said the ofv they make for my truck is a ofv010 or020 and is set at 31-32 psi for optimum fuel volume, as the pump becomes inefficient at any psi higher than that. they based that on tons of testing, and not bashing in any way. but thing is on their own site they then claim that u should run 10 psi of fp per 1000 rpm, so with my 4k gsk i should b running 35-40 psi by that standard. apparently the guy i was emailing is away and i havent been able to continue our conversation so im asking u guys-whos running this ofv and is it performing as expected with a truck similar to mine? also interested in what fp u guys are running and reason y. educate me, but pls take it easy lol

 

After having my pump rebuilt and the 4k gsk installed, I needed approximately 38-40psi under load for my truck to run correctly. I had to ditch the stock lift pump, as it would not keep up. My truck would miss/sputter above 2500 rpm. I guess I was one of the lucky ones

 

hmm did not know of stock lp not handling a 4k gsk. something to keep in mind. what u running now for a lp?
