may be you know it, in Europe our octane regular is 95 (and we have 98) , do you think that is ok for my engine vortecmax ? or it is too much ?

Higher octane fuel will not harm the engine but if it is not tuned to use it, it is a waste of money.

There is also a difference in European octane vs North American octane. Not sure the calculation though.

  So for anyone else looking into this, yes the surround fascia is separate and easily swapped. Yes i went with the denali vader chrome. Will see what happens, truck isnt on highway much and gets cleaned often. Seem as rock chips and bugs have a helping hand with the problem.

  The no sound problem is the audio amplifier. The audio amp has a heatsoak issue in some circuitry which causes it to miss the wakeup handhake. If it doesn't respond within a certain time parameter, then you get no sound. I brought it in and had the software update, but after further testing the tech made the call for a new audio amplifer. The software update I belive gives more time for the amp to respond, but if the amp is defective then you can still get no audio at times. After the update it went 12 days before no sound. After doing some research, apparently the fix is a new (updated) audio amplifer, the circuitry internally has been improved to better deal with heat. I had to wait 2 1/2 weeks because at the time, it was on backorder with no eta. Well the amp came in earlier this week. I had the amp and programming work done today. After picking it up I stopped at a few places, and whenever I started my truck, the audio was on instantly, so whatever they did it appears to work because it's never had sound that quickly......Hope this helps
