Have you taken the time to contact KKK in Hanover? As posted two years ago, I spent two hours at the KKK factory back in July of 2000, and photographing their facility for their annual report. I even had lunch with their Director of Public relations and two engineers, in their cafeteria. I deliverately asked this question, as I was considering chipping my S4. I was informed that under the proper conditions (no oil starvation, enough heat dissipation, ect), that KKK K03's can handle continuous a continuos 1.3bar. They can even handle 1.5 bar spikes. I was also informed that cool down and warm up, are exceedingly important (duh!) and that appropriate oil selection has a ton to do with warm up damage.

I am sure APR, GIAC, MTM, ABT and many others all have the KKK K03 specs, something you undoubtedly do not have!

I guess we will find out when chipped S4's start hitting 100,000 miles...

Thats just the way it is. Turbos fail. Its an absolute guarantee. And arguing that chipping won't make it happen faster is completely rediculous.

in the old-turbo-part-number days, there was speculation that turbos were blowing because of being overworked at high altitude. Supposedly, the MTM generation II chip addressed this problem by reducing boost at high RPMs. I am no expert on chips but my take is that the MTM gen II chip would be easier on your turbos than other chips which make more power.

that your turbos will NOT blow? Your saying chipping your car won't even increase your chances of blowing your turbos? Your saying that a chipped S4's turbos will last as long as stock turbos?

System_S4k

Agreed.

Not that I mind the debate, but I really would like to know the "safest" option. Not just "keep your chip if you're not prepared."

If I do chip, I will be prepared, but I also think that minimizing the strain is prudent for my approach to chipping.

Every part on a vehicle has an average lifecycle. Theoretically, chipping WILL cause them to fail sooner than they would fail running stock boost. Whether that is at 50k miles or 500k miles only the manufacturer knows.

We could argue about how coilovers will cause suspension components (arms, bushing, etc.) to fail prematurely too....

The reason AOA attempts to combat chipping is because turbos are a lot more expensive to replace than bushings are.

The bottom line is no one here has any proof or factual data showing chipping correlates to a significant reduction in turbo life. And no, a very rough "chip survey" conducted by enthusiasts here is hardly enough to call valid.

I found this page somewhat informative. Note how it mentions overspeeding at high altitudes, etc.<ul><li><a href="http://www.treasurestate.com/diesel/turbo4.htm">http://www.treasurestate.com/diesel/turbo4.htm</a</li></ul>

I am planning on going w/Neuspeed. not as much boost, but easier on turbos. stiil adds 55hp/65lbs
