I am a new owner of a 2016 Longhorn 2500 with 31,000 miles that has been deleted, air intake, 5 inch straight exhaust, with EFI live from Hardaway in Florida. I immediately had to add a muffler. Still may add a resonator. Hardaway would barely give me the time of day on the phone. I know nothing about the tune except that I have it set on level 1. I always hear about how improved mileage is from friends who have done this. I don't see any improvements. Is it safe to use the level 2 for towing? Will levels 3 and 4 blow the motor without other upgrades. Do I need new tunes? I know nothing of this world. I may end up selling it if I can't get comfortable with all these changes. Any good advice is appreciated, tune recommendations, etc. Several mechanics have told me that the truck will last forever now.

Will not hurt anything. J I’m have 75HP tune haul things daily and never worry it’s how you drive it Don’t hammer the go peddle and you are fine. Far as mileage It’s how hard you drive. Ease on the peddle and it will do better

 

Congrats on the new truck! Here are a few things to keep in mind to help you get the most out of your setup:

Fuel Economy: Aftermarket tunes and deletes can improve mileage, but it depends on your driving style and how much load you’re towing. If you're not towing heavy loads or driving in a way that puts the truck under stress, you might not see much of a change. Try driving at a steady speed and avoid heavy acceleration to get better mileage.

Towing on Level 2: Level 2 is generally safe for towing, but it depends on your specific setup. If you’re towing heavy loads, you might want to monitor EGTs (exhaust gas temperatures) to ensure they stay within safe limits. You can upgrade your exhaust and cooling system if you plan to tow a lot.

Levels 3 and 4: These higher tunes can add more power, but they can also put more stress on the engine, especially if there are no other upgrades (like better cooling, a stronger transmission, etc.). You don’t want to risk damaging the motor, so it's best to leave it on a lower level unless you’ve made other supporting upgrades.

New Tunes: If you don’t feel comfortable with the current tune, it’s okay to ask a reputable tuner to take a look at it and make adjustments. A good tune can help improve your driving experience, fuel economy, and engine longevity.

Long-Term Truck Life: If mechanics say the truck will last a long time, that’s a good sign. Just make sure to keep up with regular maintenance (oil changes, filters, etc.), monitor engine temps, and drive responsibly.

If you’re unsure about the changes or the truck doesn’t feel right, it’s okay to consult with a professional tuner to ensure everything is set up correctly.
