18 pro 4x deleted for almost a week now. Took her to HunterXD and absolutely couldn’t be happier with the result as well as his knowledge and helpfulness. A great guy to have do your work for sure! Thanks bud! I’ve been stalking this forum since late October last year when I knew I’d be bringing it home. It is an awesome place to look for info on these trucks (also to laugh at a couple dumba** posts). So thanks to all of you for the help really. As far as the delete I did a flo pro full 4” system with muffler and an ezlynk tune and SOTF switch. I started with the 1.4 tune which was an awesome upgrade from my sprint booster/stealth module setup. I’ve since gone to the 1.9 tune (Wow) and now am running the 1.9.4. (Wow with smoother shifting). I did run the sprint booster at first but like it better without it now. I run my SOTF switch at 4 then switch to 2 or 3 for towing to be safe. The truck pulls and just keeps pulling! Very little if any lag. Fuel mileage is approximately 2 MPG better but I did do more than a few hammer down runs. It’s too fun! The sound outside is definitely a louder whistle with the flo pro, but it sounds awesome! I absolutely hate annoying loud exhaust systems on anything, but this sounds really strong without being obnoxious. Inside cab noise is barely, if any, louder than stock. I do find myself turning off the radio and cracking the window just to listen now. I’m very happy with the flo pro and muffler system. I did have some issues with ezlynk on IOS this week but they have fixed that with an update and even emailed me to let me know it’s been resolved. Truck is so much better to drive now, tows better, sounds better, fuel mileage better, no regens. If you’re thinking about doing it, stop thinking. You won’t regret it. If anything changes or I get some updated results I will post. My stealth module is for sale and my sprint booster will be now too. Thanks for reading guys. Thanks again Hunter XD as well!
