I know some of you are using a dsp switch and running tow and economy tunes. Would like some real world comparison. I'll be getting my ecm tuned soon and debating whether to go dsp switch or not. I don't really care about extra hp. Looking for towing and economy. My truck tows my signature rv to job, then it's my commute vehicle until next pull. I follow construction shutdowns. I do also cross country runs on major holidays. Home in NC.
