Are there any drawback with a tune

[Ron Burgundy]

The usual first power mod is CAI and exhaust and dyno tune.

The benefits are evident.

For those with tuning knowledge, what exactly in addition to fuel maps etc is also changed.

If the tune is done well by reputable tuner are there any negatives with dyno tune ?

Any components that would suffer as a result of a dyno tune ?

Pros: everything
cons: paying over $2.08 per liter for 98ron, well that's what I paid the other day. Most I've ever paid per liter.
A tune mostly advances the timing over stock to take advantage of higher grade fuel.

If it's auto depending how they tune it and the torque management can reduce the life span. Apart from that no , I've always had better fuel , performance and cold starts if done right.

What is torque management about ?

Just make sure they don't go for bragging rights at the pub on a Friday night type tune, like mine has. Although this may not be an issue unless it's cammed as well, where they push the power band out to max hp where it's of no use on the street.

I guess its around when the converter locks up. I'd imagine it would accelerate wear?

Not an autobox man though!

Mine only has OTR CAI and tune. Done by Sonny at Autowerks.

Just curious if there is driveline price to pay for extra power and torque.

They can explain it better than I can without just directly copying.

Zero price to pay with respect to driveline if you drive your car sensibly on public roads. As long as you don’t accelerate at WOT at every set of lights and stay within the speed limit, you won’t get near maximum torque levels pushing through the driveline… = long life but boring

Put another way, even a race cars driven without mechanical sympathy will spend a lot of time getting things fixed

They can often turn off or hide faults and codes from appearing and causing issues.
Like O2 sensor faults due to cats.
Or turn off the Maf Sensor (changing to Map) and tune out or turn down other sensors, But each tuner may do different hings.

I found my SS is a bit nicer on fuel on the highways but also a bit worse around town driving since a tune.
All stock except a full exhaust, so no accompanying mods that many end up doing before a tune (it was mainly to turn off o2 code faults from cats)
So thats also something to consider depending on how they tune it
