I have read a few threads regarding ecu tunes but haven't seen too many people that have tuned their 2013 GL 350/450/550. 6-9 months ago there were fewer options for tunes. It seems a number of vendors now claim to have tunes available. Prices vary quite a bit across vendors however.

I'd love to hear from anyone who has an ecu tune on their 2013 GL, what vendor you chose and what your thoughts are.

If there are vendors here on the forum who can explain what options they have available, what makes their tune good (better), prices, anything that can help members interested make a decision.
