Its looks pretty tempting to chip the S3 using one of the well known chip tuning firms (superchips, revo , amd etc ), and get 300bhp for not much money, especially having come from many normally aspirated cars where those sorts of performance increase costs lots of money. But how reliable are the cars once they've been chipped?
Are there many cars out there that have done significant mileage with no premature wear on the turbo or engine or gearbox/haldex diff, I'd expect things like the clutch to wear out faster but they're consumables anyway.
How much real world experience is there out there? I'd presume not much given that the s3 hasnt been available for much over a year or so, I guess the biggest mileage we could expect to see is about 50000, but theres probably not many people doing that mileage that have a chipped car.
Its pretty clear that it will void the warranty (on the engine and drivetrain at least) if the dealer knew about it, but if I had my car chipped I'd not want any increased likelyhood of actually needing the warranty. Is this unrealistic?
Presumably if the car was chipped, it would be good practice to lower the service interval, or at least change the oil more frequently, any thoughts?
