I think my truck has a tune

And you will see a difference in 93 vs. 87, as the PCM will advance the timing.
One fairly reasonable giveaway would be the shifting. Most tuners will cause the trans to use every gear, even if Sport mode isn't engaged. Watch the dash (hit the + button if you don't have the gears displayed) and see if it's skipping shifts 1-3-5 under medium throttle.

Is there a definitive way to tell, without ratting myself out to Ford?

Another way is to look at the brake pedal switch. Down by the left side of the steering column, look for a white electrical box connector thingy, if the bottom connector is pulled it will defeat *** too.

My truck is a 2015 3.5 it runs so good I also wonder if mine has not already had a tube. I don’t think it ever skips a gear though. Only owned it for three months and never drove a 3.5 before. I notice my truck never cuts the motor off at a redlight so I assume something has already been altered.only got 16.3 mpg first tank of gas with 74,000 miles on it.

Often times you can tell if an Ecoboost truck is tuned also by trying to boost launch / brake boost it from a dead stop. Typically calibrators will make adjustments to let the truck leave on boost which is pretty noticeable when comparing to a bone stock truck. One other way to know for 100% certain if the truck has a tune would be to pull a read from the truck's ECU with a tuning device and have a calibrator compare the read to a completely stock tune with that same exact strategy code. We could get you set up with one of our Mycalibrator Touch tuning devices and ship that out since I see you're not local to us here in Michigan. Otherwise I'd say to bring it down if you were local and we could pull a read. Then once you received the device, simply plug it into the truck and save the stock cal read. When finished you'd update the device online using our Mycal app to export your read to the cloud so we could take a look at it.

op here reporting back. truck maxes out at 105/106. So probably no tune so wow it's a fast truck.
SO now I'm curious. THe power delivery seems pretty linear - I love it. SO much torque down low. Really not much advantage to pushing the pedal to the bottom. Just keeping it at 60-70% it stays in the torque band and just flips those gears around 3-4k rpms with just bushels of ftlbs
SO if I did a tune, does the addtl torque stay pretty linear?
