![]() We were still getting 1093 codes like crazy and even got the occasional P0087 code (fuel rail/system pressure too low). (A twin CP3 system works the same way, only each common rail has its own fuel pump and high supply of fuel.) While on the subject of fuel, we also found a couple of other problem areas once the turbo and modified CP3 were installed. By feeding both rails, that problem is eliminated. The Superchips tuner was not included when I bought the truck, but the performance seems like the tune may still be installed in the ECM. The previous owner appears to have put a Superchips tune on the truck since there are Superchips stickers on the truck. The theory behind it is that while the left side common rail has plenty of fuel, the last two injector lines on the right side common rail can starve for fuel under load and with hotter tuning. I just received my PPE Standard Xcelerator tuner. The dual-feed line feeds the right side common rail straight from the CP3 pump, so both rails are being fed simultaneously with identical pressure. ![]() The four injector lines on that rail are fed and a fifth fitting allows fuel to travel from that rail, across the top of the engine and into the right side common rail. 849.00 SKU: 111035000 Product Highlights: 01-10 GM Duramax LB7, LLY, LBZ, LMM Race Works as a Hot tuner for the classic Duramax and Race tuning for the 07. On a stock Duramax (LLY and LB7), the fuel leaves the CP3 pump and enters the front of the left common rail. ![]()
