I recently purchased a 05 250 cc sb lariat. it came with aftermarket cold air intake and 2.5 inch leveling kit. I recently purchased a mbrp turbo back 4 inch exhaust with cat delete to help with performance, not yet installed, hopefully tomorrow. I am looking to help with preventing any egr problems in the future. I have plans to tow a fifth wheel camper in the future. Can anyone sugggest any other mods that may help with performance, mileage, torque. i dont have the funds right now to do studs in the head. I was seriously considering a sct tuner with ability to turn off egr, or is a total delete better. not really wanting to tune jsut wanting a tuner to cut off egr, reason being dont know enough about tuners. are they good for the truck or does they cause more damage in the long run? I noticed that BLE came out with a egr delete in January. Is that the way to go? gauges? Need suggestions on what works from all the experience here. Sorry for all the dumb questions, just trying to do what is best to make this truck last a while.
