I've been reading online alot about the c15 needing a fuel pump/transfer pump spring update or shimming due to low fuel pressure.
Is this a option on a 2008 c15 sdp engine or does it have a different setup?
I am having low powe and boost issues and am going to check fuel pressure tonight but just curious if the fuel pressure can be mechanically adjusted or if it's all computer on these ones?
What should it be at? 75 idle, 110 @1800?
Engine has 700 horse with a bypass done so i need that extra pressure I assume.
Thanks
