Ok, I need help. I have been searching for a se of injectors but I dont want to spend alot of money. DPP Power has a set of DIY Injectors for only 250 and there machined plungers and barrels for another 200. i have rebuilt several cummins and duramax injectors and they work great. I know the psd injectors are alot more complicated, but I know I ca do it. Is there an one running these and what type of problems do you have or posative thoughts?
