Find a new tuner. If your injectors are maxxing out, then you replace injectirs, not add another inline pump. If your pump is failing to keep up pressure then replace the pump.My tuner told/showed me on the Dyno that my injectors are pegged real early. I have a vortech s trim w an in tank pump and a T. rex pump. He said I need a 3rd pump(booster pump). Any ideas?
