Isn't the great thing about the IS overboost function that it only works at lower RPMs and hence is more gentle to the turbos than stage 2. Ie it increases boost temporarily to ESS stage 2 levels at lower RPMs but keeps HP at higher RPMs at something similar to ESS stage 1? This combined with the fact that the overboost is only available for a short period means that you are getting a very reliable tune similar to ESS stage 1, but with temporary stage 2 performance available where and when safe.

It would be nice to have this as a "35isHADOW" tune, but I would still want the added responsiveness of the ESS tunes mixed in. Also it would be nice if the availability of the overboost programme would actually depend on factors such as oil and water temperature instead of simply a fixed set of seconds.
