hello everyone. Thank you for all of your information on my last post, I wanted to pick your brains again. My first question is in regards to the performance chips I keep reading about. Are these worth the money and do they provide improvement they claim? Which is the best one for my 2011 5.7 Hemi?

Second question is in regards to my navigation system. Is it possible to get an updated map and if so where? Hope everybody had a great holiday and thank you again for your help.

 

Personally I would not update the maps unless you know drastic changes to the roads since 2011.

If your unit is a Garmin you can contact them or your dealer should be able to tell you where to purchase the disk. From what I have seen the disc is in the $140-180 range.

For that I would buy a portable garmin nuvi and have lifetime updates for free. In five years I have only updated my portable once.

I can't help you on the chip. My hemi is stock.
