You guys are quickly becoming the go to aftermarket house for AMGs. Congrats .
Unfortunately it appears you have gotten on the Rennteck route with your pricing
Amazing gains - I can only imagine what the track times are.... pricing is commesurate with the gains for early adopters. Pretty soon we will see every swinging dick aka tuner with a file. This is first run so I think its fair especially for the r and d invested in the the M178 and hp/tq gains.
Great work! I'm assuming MB wouldn't cover under warranty any damage to the drivetrain with these mods intact?
Have you had a chance to test it on the track to determine acceleration gains?

Weistec Engineering
hey Weistec Engineering, I am interested in buying and installing the ECU Calibration.
however, I am located in UAE, can you let me know how to install it?
and most importantly, is it detectable by Mercedes dealer when i send my car for service?
this is becuase if it is detectable by Mercedes dealer it will void my warranty.
can uninstall it before sending it for service and reinstall it after service?
please provide me with your expertise and feedback

If you're a Mercedes-AMG GT S owner and you think more power and an even deeper, more frightening snarl of an exhaust note would make it just right, take a look at what Weistec has developed.

I have to concur with the review of Weistec Engineering. Fortunately, I was introduced to them through an excellent AMG technician. After having their ECU upgrades on a series of cars, I had the pleasure of discussing their product(s), unofficially, with a senior factory representative at an AMG event who indicated affirmatively, smiling, when talking about "tuners" for Mercedes vehicles. Weistec was the only one given that positive an indication, and this guys knows the "players." Others in the market don't do the engineering, R&D nor have the technical expertise to achieve optimal results for the vehicles, like the Weistec team under Steve's leadership.
This is not a "add-on/bolt-on/piggyback" solution. Weistec is an integrated engineering solutions that don't push for numbers (while they are impressive) but preserve the around town functionality in normal driving conditions with a more response accelerator feel. When these cars are "driven" the responsiveness, feel and results are amazing, definitely developed to factory standards.
Their website and marketing is impressive, this is because the Team is passionate about what they do and stand behind their products. I don't typically endorse products or businesses, but this is a case of talented professional car guys delivering engineering quality that is developed in Southern California and delivered domestically and internationally.

Weistec is the only smog conscious company that makes parts for our cars. The SLS 750 supercharger system is 50 state legal. Go with what makes proven power on the M156/M159. Check it out for yourself.
I'm getting the tune this week and will report back this Friday when I drive it. I opted out of the downpipes at the moment since they were major $$$. Maybe that will be the next mod. ..
