Depends on the 6.5
Matt, I agree a bit more pressure might be a good thing, but that sounds like the same performance I'm getting from my FRB-5. I'm generally 5-7 in normal driving, and on a hard pull 3-4 psi. So, I'm still not convinced that the FRB-28 or your custom pump really have better performance. Not trying to argue, you have a good point that a bit more pressure would be a good thing for the IP, but I think the steadier pressure and higher volume that the FRB-5 gives over the stock filter does the job.
I don't know if this is a good analogy or not, but here goes ..... everyone agrees that a 4" exhaust gives much better performance than stock, but that doesn't mean a 5" exhaust will give you much more than the 4".
I'm not convinced either. I'm just happy they made good on the pump I should have had from the get go.
It'll be interesting this year to see what the diesel does in the frigid cold. That is the only reason I could see more pressure helping.
I have absolutely no idea if more PSI would do anything different to the IP or not. I just like the thought of the IP opening up, and the fuel being pressurized in there safely of course. The less work the IP has to do, the better is for sure.
