Even if the tune was say $1100... I'd be willing to pay an extra $100 bucks to gain another 5-10kw atw's... Wouldn't you?
Peak kW isn't everything when it comes to drivability, delivery of power, fuel consumption. More power can be had by running a bit leaner or more boost but these things can lead to running too hot and shortening life of engine components.
Personally, I err on the side of caution. I'd trade 5kW for 50,000km more engine/turbo life.
I DO agree with you though, if it was me, I'd top up the extra $100 for a full custom tune. But then again, I'd also make a few minor mods before I did that, so it's not a fair comparison.
The key thing is, peak kW mean NOTHING with a daily driver. Look at all those VVTi/VTEC cars. Big peak numbers, drive like civic/corollas off cam.
All modern cars DO NOT come out of the factory pushing their full power potencial. They are all de-tuned for people that are likely to not service their cars on time, not run the best quality oils & fuels etc.
For example, the MPS3 runs extremely rich up high as a safety precaution... But a retune corrects this & obviously results in better power & runs nice & safe (Not that the MPS3 needs more power
I had my Lib custom tuned back when it was 100% stock & the power, drivability & fuel ecco were all increased.
Most tuners these days (Unless advised) will tune the car to a safe level to give it better performance, but not push the limits of the hardware. A good tune is the ability to get the most out of what's available be it standard or modified. If you look after you car & service it on a regular basis, I cannot see why a tuned couldn't last as long as a completely standard car... In fact, there would be potencial for a tuned car to outlast a standard one because they would be running more effeciently & therefore cleaner.
At the end of the day, just because your running say standard boost, doesn't mean your not going to destroy your turbo in 50,000kms... It comes down to how you drive it, weather you let the car warm up / cool down etc etc etc.
