He does not sound like her want your business. If I was not in CA, I would have deleted ASAP. Do the delete an tune if you can and you may fined you don’t need more than that after you install the tune. If not then add a throttle enhancer like iDrive on and that will fix the rest.So I just decided recently I wanted to delete my truck, I went to a reputable diesel shop in north Texas and he relayed he highly recommended I didn’t do a delete and tune because Titans according to him have a tendency to fall apart immediately. And I’ve done some research on my own and haven’t found that at all. I’m looking more for a economy tune, increase the drivability and decrease throttle lag and finally to hear the turbo a lil more. So far the EZLynk looks like the way to go but if somebody could help me out by corroborating this info or debunking it I’d appreciate it.
