I have a 06 LBZ Crew cab short bed 4x4 lifted on 35"s. Currently has a 4” MBRP exhaust, AFE cold air, EGR delete with pressure pipe Intake and heater grid delete. I'm in the process of doing head gaskets. That’s a whole other story there, no problems found so far. Since I have the turbo off I have decided to replace it. The truck is a daily driver with occasional towing duties. It will be getting EFI live eventually, but not right away. Bigger injectors are also in the future plans along with a Trans build. So I have looked at a Garrett 4094R both T4 and non T4 kit. Have also heard people mention the S366 and the Cheetah from Fleece. I do want to stick with a single I think. From what I have read twins can be a PITA to tune for. What are some recommendations for my application? End goal I’m thinking 600 -700 HP is enough for my needs maybe more than enough if there is such a thing. Any advantage to a T4 flanged kit over a drop in?
