What is your take on this tuning kit for the 4.2 TDI ?

if it sounds too good to be true, it likely is too good to be true.

is a twin turbo 2.7L motor. I am running an APR chip and it is increasing my hp from 250hp to 308 hp in 92 oct. mode. More importantly though, it is boosting my torque from a stock 258 lb. ft to a whopping 366 lb. ft. of torque. These kind of figures are much easier to obtain from a turbo-charged motor than a normally aspirated one. The quickest way is to just increase boost. The better tuning companies do more than just increase boost, they do it in a way as not to over work the turbos which can lead to premature failure.

I think more importantly is looking at the boost in torque in the 4.2 TDI, what a beast that must be.<ul><li><a href="http://www.goapr.com/Audi/products/ecu_upgrade_allroad.html">http://www.goapr.com/Audi/products/ecu_upgrade_allroad.html</a</li></ul>
