Has anyone here tuned their car? (tire, tuning, exhaust, engines)

tuned my sound system.

Unless it's a drag strip truck, you should not be running it full bore on a daily basis let alone weekly. I'd imagine drivers want this for the driving dynamics: acceleration "like you're towing nothing at all" and perhaps end up not downshifting as much up grades.

Take a diesel good for 400k-500k and give me a FUN 250k? Sure.

I was talking about tuning through ECU programming. Did this with my 17' Honda Civic 1.5L turbo recently. Feels like a night and day difference. Added maybe 20 HP, reduced turbo lag. I never have to hesitate when merging or passing, which is nice.
Defiantly a good purchase. Using a KTuner with 93 octane, and just sticking with what's included, no custom tune. As far as durability goes...the car is almost payed off, and I've done a lot of research. I'm comfortable with what I've done, and don't plan on getting flex fuel kits, intakes, exhaust mods, etc. The only cars I've heard of getting messed up are people heavily modding, messing with their own settings, 2 stepping, increasing PSI way too high, abusing it in other ways.

I put high altitude jets in my Jeep carb and it runs way better @ 7000 ft and gets better gas mileage.

I used to change my points and plugs.

That actually sounds interesting. If I can get moved to somewhere with no emissions testing, I'd really like to build my own modern turbo system. It's amazing how far people can take things before they start needing to put together stronger bottom ends, deal with the simpler things like ring gap, really crank up fuel flow, etc. I appreciate the concept.

I figure that anybody who wants to do this needs to get going before we are swept up by autonomous vehicles, electric cars, strongly enforced national rules on cars with internal combustion engines. Have fun while there's fun to be had.

Well, to old farts like me, "tune" means adjusting idle mixture and the second stage linkage, points, condenser, plugs, and maybe wires, and timing. Synchronizing carburetors if you have multiple. Adjusting the needle position on SU carbs. New air filter, maybe fuel filter.

Modifying the engine in any number of ways is "hopping up" the engine or "hot rodding" it.

Blueprinting is one thing that can be done in the course of hot rodding an engine; balancing is another. Porting and polishing are two more.

All these things have specific meanings, not generic ones.

If you twiddle with the electronic engine controls, you're going to be giving something up.

I’ve had lots of cars tuned (ECU) with some good results... most recently a really mild tune together with a better air intake of a F150 3.5 ecoboost achieved around 510 rwhp. Stock was 450hp at the flywheel so a pretty good and noticeable increase.

I've got a tuned 2001 VW Golf TDI. The stock ECM allows for fuel quantity, engine timing, and idle speed adjustments. However after installing larger fuel injector nozzles, I decided to buy a flashed ECM that adjusts the boost map for more power and yet lower fuel consumption. It adds about 30% hp and 80% torque with the larger nozzles. Unfortunately I've learned that many states will fail the car during the emissions test as they can detect modified ECU/ECM programming. Luckily I held onto my original ECM and swap it out from time to time. Frankly, I find the car undriveable with the stock programming.

I know BMW, Subaru, and other tuned cars face the same issue. I decided to leave our Fiat 500e and Tesla Model S 85 stock

Yes.
