So I recently started hauling (part time job) hay/straw for race horses in Lexington KY. I. Pulling 28-30 ft gooseneck trailers with approx 18-20k lbs. Talking with local boys and stating my mileage is shit, they stated do an EGR delete and PCV relocation. My question is do I need a full EGR delete kit or just a block off plate? I'm not looking to race or blow black smoke on everyone, just want better mileage and torque. Any help or suggestions is appreciated.
