Ok I am getting ready to upgrade my turbo. I would like to have 350hp. I am going to use the new era 370 sticks. I have the Powerstroke intercooler 2nd gen air intake horn 2nd gen cast elbow on the rear of the turbo with a 4" down pipe into 5" just past the firewall all the little pump tweaks timing bumped an 1/8" homemade cold air currently I am using a factory style wix air filter with a swiss cheese factory air filter box Denny T stage 2 fuel pin 3200 rpm gov spring. I am pretty sure that just a turbo upgrade and all the little things I have done aren't going to get me to 350hp but which will get me closer? I want the 14cm2 exhaust housing but is the one Gillet Diesel Service sells that much better? Or should I go with the the one that Pure Diesel Power sells? I also want to upgrade the compressor side. Who should I get the compressor upgrade from. Or am I better off getting a completely different turbo? Thanks a ton. I really do appreciate all the input from you guys.
