I have a speed density 93 lighting. I have been avoiding turning it to mass air, because I believe with decent tuning and a custom chip you should be able to get the system to work well. But I am wondering if this is to much injector for the 450+ horsepower I am making. When I turn the fuel pressure down to around 24 pounds the truck runs great, but I have an occassional lean back fire, when I turn the pressure up to 34 pounds I have surging idle, but boy does it pull hard. With the nitrous I am running, the lean backfire scares me, but the surging idle around town is a pain in the a**. Any ideas, short of switching to Mass Air. Thanks guys.
