Could be worse!
I am in the process of getting my motor tuned and have the 5 gsk kit from Columbus Diesel on a 175 94' pump with cut DV's, rack plug, dual -6an feed, .093 holders, .093 lines, no plate and 55psi at idle 50psi WOT for fuel. The truck runs hard up to 4,000 and then just holds and maybe gets to 4,200. I would like to get this thing to run 4500 if I gave it a couple of more clicks on the springs would that help? And yes the rest of the motor is built to run these rpms.
Thanks
