Everyday tyrant tune
Just curious what guys/gals go to everyday deleted tyrant street tune is. I have stock,tow,street,performance and I think the top hp is called race?. Anyways Ive been keeping it in street all the time except when towing. Curious what others do. Not looking to get on it hard or anything but wondered if going up to performance for my everyday driving tune would be good or bad in long run for the truck. Dont need to blow my turbo etc. May upgrade turbo sometime down the line but with 30k on odometer Ill keep it a while. I try to stay under 25psi boost all the time.

I don't want to run a tune where I have to self limit for daily driving or even hooked to weight, obviously within reason. Worth adding to your considerations. What I mean by this, I want to be able to insert my truck ahead of a long string of traffic and get out of the way without worrying if boost will hit 27+ PSI because it won't.

Thanks!
did a little more google searching. Many keep it in performance because the fuel mileage is better. I didnt buy truck for fuel mileage but thats the reasoning. I did put it in performance yesterday,unless I keep the throttle buried im not really going much over 10 psi boost driving normal. Quickly pulling out you get up to 15-18 psi. Buried of course you can get close to 30 quickly. I dont drive it like its stolen. I have done some hand calculations before this and the tow tune really is pretty crappy on mpg. I had it worse then stock in my calculations. Performance was about 2 mpg more. When pulling my 15k fiver tow tune avg mpg was same as stock.

Vs what it was stock? I only have 1 month of calculations since deleting it. Keeping in performance tune Im about 2mpg better then stock. Street tune or tow is about same as stock. Stock was 14ish. Now its 16ish. No flat land in my area. Always going up hills. I didnt tune to get better mpg. So as long as im same or better then stock im fine with it. Of course driving style effects it greatly. But like ive said I drive pretty conservative most of the time. The dash mpg gauge has me at about 17mpg. But hand calc is 16
but...... I havent driven long enough in all the tunes to say these are concrete numbers. Not by a long shot.
Im 100% happy on how the truck,sounds,performs etc since deleting. Thats concrete!

Yeah I had truck for 7 yrs. I just recently deleted because I was out of my extended warranty. I must say it was like I git a brand new truck again. That grin you get when you go on your first drive. Completely different animal now.

I was behind a 11 to 16 Super Duty that was deleted today. Looked like a younger guy. When we pulled away from the red light, it puffed some black smoke and he didn't even accelerate all that much. Then when we were coming to another red light, it was puffing black smoke as we were slowing down. I'm wondering if he had it in tow/haul mode like I drive mine in and it was puffing when the trans down shifted. I'm thinking he had it in a higher tune.

This doesn't always mean a hot tune. That is my one complaint even with a 0 HP "stock" tune. Accelerating to 30%+ engine load causes smoke or normal accelerating out of a coast such as after a turn causes smoke. It isn't that hard to hit 30% engine load. I cannot see any smoke at WOT once moving. I think this job 1 turbo is just a little slow to spool and clean it up. It is easy to prevent the smoke, just have to ease into the throttle which changed the way I was used to accelerating a little. Once moving, I can WOT from 2nd if I want and other than the noise, it's fine.
The other thing I learned is lugging the engine causes smoke. Older diesels did this, I guess I thought our newer pilot injection diesels were magic or something...(/s). For example, a slight incline on a less than 50 MPH county road in 6th (where it wants to be with factory programming) but not enough to downshift I now assume helps add soot to the DPF based on what I can reproduce now.
Mine does not smoke at all lifting from the accelerator, it just barks/growls. Likely a hot tune or issues though.

Your 2nd paragraph talks about why I drive mine in tow haul mode and I lock out 6th on the local roads. Sometimes I even have to drop it manually into 5th to prevent low RPMs which lug the engine.
But that deleted truck sure sounded like a beast. I lowered my window so I could listen. The 6.7 sounds AWESOME when deleted and breathing freely.

I just lock out [D] 6th in those lower speeds. T/H downshifts were too much when empty (not harsh just annoying). I used M a lot with stock programming so would keep it in 6th for probably too long. New programming doesn't shift to 6th until about 53 MPH or so which works well on 45 MPH two lanes. I've actually not heard my truck from another vehicle yet post improvements but it's loud WOT next to a board-to-board type fence.

I havent even put the hottest tune on the truck and I prolly never will. I dont get any black smoke when normal driving. I have to stomp on it to create any. The turbo whistle is music to my ears against a guard rail,lol
