Is this for the same thing everyone is complaining about?

I called my local dealer, sent him the above link and still they have no idea what I am talking about. Would a DINAN software upgrade do the same thing?

Dinan software will do the following:

Performance Engine Software extracts additional power as well as improving drivabiltiy. The software safely raises the rev-limiter by 100 rpm, enabling you to carry more road speed in each gear, as well as optimize shift points. The top speed governor has been removed, enabling the cars to reach their natural top speed. Revised EML tuning provides improved drivability by speeding up throttle response.
