Just watched the videos.
suggestions from my end would be to give an occasional reference of the RPM and the speedo to have a better idea.
Also keep the window closed while filming. I assume you dont smoke :).
And turning on the AC while climbing, since unfortunately we pakistani's need to run the AC on most of the time due to hot weather conditions.
just for reference i happened to be on the same route that day toyota were testing their new corolla test vehicles in ISB on the Monal route and they really smoked it several times just to make sure that vehicle works perfectly on the climb and it does.
