Considering getting a W463 soon. More than likely will be picking up a g550.

was looking into getting more HP and found this online.

$1500 for about 140 gain in HP and 200lb-ft increase in torque. Sounds like its worth it to me.

Are these tunes realistic? safe? Anyone have experience tuning their g550 for more HP?

Tuning the twin turbo V8 is proven.. I would look at Renntech too!

I got a eurocharged tune on my G500, and while obviously not going to have the impacts it would on a turbo motor, it runs better, sounds better, pulls more aggressively in first and second due to the mapping, and has been getting about 1-2 mpg better since. I think I only gained 20 hp and 20 ft lbs but it was worth it, and the flexibility of their tool is very nice, particularly considering the price.

I like that you are local.
i was on your website but couldn't really find anything specific for a 2013 g550. Can you tell me the exact gains in HP and torque you guys can achieve for a 2013 g550.

thanks

I had Kleeman flash my 2010 G550 (naturally aspirated V8) for under $1000 and there are pros and cons to it.

Granted, all of this may be different for the newer bi-turbos but I find that, after the flash, the transmission stays in gear much longer while full throttle (into the redline) and that has taken some getting used to. Specifically, at times, I have to shift manually or with the accelerator by letting off a little bit so not to run the RPMs too high.

Other than that, my G is noticeably quicker and sounds phenomenal. The numbers likely went from around 380hp & 380lb-ft to above 400 for both.
