Performance upgrades for X164 Gl550?
We are about to pull the trigger on a 2012 GL550, and I've been searching all over the internet with nearly zero luck. All I found was a $1500 tune on vividracing.com and that only gives me 20hp...I know this can't be the case. Are people just not making their GL's go faster? Is this not America? I know they have used this engine elsewhere so can I use other mods from other vehicles? Any help would be great.

There are no cheap mods that are worthwhile for making significant power gains on the 164 550. You may be able to find a x166 GL450 close to that range. The 2013 and 2014 had the same engine as the 550 but with a different ECU tune.

No, it's not that we don't care. There is just nothing worthwhile unless you throw a supercharger or twin snails on the engine. If you want to do that, will be cheaper to upgrade to the x166 bi-turbo V8.

'07 GL450
Have you looked into the SprintBooster?

I had one on my 2007 e500, and moved it over to my 2007 gl450. It takes away that 'laggy' feeling when you hit the gas, and makes the acceleration really peppy/responsive. I wouldn't drive without it.
I would urge caution though (it may take some getting used to); with great power comes great responsibility....

This is what I've found though...http://www.execstudio.com/products_power_kleemann.htm
Looks like this would be my best bet?

There is a 2008 GL550 with a Brabus Widestar Kit for sale for 20k. It's pretty rare. Search cars.com

2012 GL450 (X164)
https://www.chipyourcar.com/
I have a 2012 GL450 - added this little ECU tuner and WOW! Took a chance on their level 3 chip and was pleasantly surprised. It's not going to rival a supercharger, but you'll definitely notice it.
Well worth the price and if you drive any distance, you'll appreciate the 22+mpg on the highway...
Hope this helps

How long have you had it? Does it stay plugged in?
