    Default Help with rail pressure

    I have a 06 Cummins I've tuned and have it running really well with 90horse DDP injectors. I have turned the rail pressure up some and seems to keep up pretty well. 130K on the truck. injectors are new from DDP also when I installed a Fass 150 and that helped a lot. what can be done in the tuning to get every bit out of the stock pump? I tweeked the Ma table for the FPR and at one point it surged bad so I went back to a previous tune. what other tabloes can help with this? thanks.
