It certainly is for somethings but I couldn't find any information on any chips on aulro. I believe it's short sighted to say that is because there is no such thing as a good chip. Theyre not all a resistor in a plastic boxQuote:

i've got a bridge to sell you. on the other side of the bridge is a snake oil factory.Quote:

Steinbauer claim up to 20 percent improvement and not to overstress engines. I'm no expert so others can comment on that.

Put simply - any tuning will reduce engine longevity - by how much depends on how it's done, to what extreme etc.
It comes down to how long you intend to keep the vehicle, what loads it's placed under during your use, and how it goes about doing it.
If you aren't completely modifying to signals for timing, boost, injector pulse width etc then you are doing your engine a complete disservice.
Just winding the Rail pressure up stresses the pump, adds pre-ignition to the engine and runs it hotter.
The TDV engines are multiple pulse, having these timed correctly is critical to keeping the thing alive.
An hour or 2 on a Dyno will never be satisfactory for all occurrences.
Changes to Smoke Adjustment tables, high load, high ambient etc are all required to keep the engine in check. A box can not do this.
That box has $20 worth of parts controlling a $18k engine... and a fixed table - if x=? Then y=? Regardless of temperatures etc.
Even a "generic" tune has had significant dyno time - usually hundreds of hours - to modify more than the base fuel table.
The cost comes into the research, the tools and the IP related to the adjusting of smaller tables within the ECU resulting in a smoother, low stress tune.
As a side note: I no longer tune engines - gave up years ago - to time consuming with other work commitments...
There's a lot invested into making it happen correctly - get it wrong and engine wear increases are significant.
Will they show up during the time of ownership for the person who had it done? Can't be certain... but I would certainly avoid buying any vehicle I found to have been fitted with a Box over a professional remap.
Having said all that - if you're happy with how yours goes - and with no EGT, no regular boroscope checks and no oil analysis etc you won't ever know... until the day it needs a tear down...
A prime example of bad tuning is a TD5 owned by a member of this forum... he had a poor tune fitted which destroyed the engine in under 6 months. He now has a rebuilt engine with a full remap - all the sub tables correct this time - and it's showing no anomalies in oil analysis for excessive wear etc.
I don't have a horse in this race because I have never added a performance "Chip" to any vehicle I have owned or gone down the dyno tuning route either.
I am of the opinion that the stock engines are designed with a balance between longevity and performance as a target and IF you wanted more power then get a bigger engine fitted.
Tweaking and forcing extra power out of any engine must wear it out faster regardless of what method is chosen, That's just common sense.
