Hi everyone!
Figured I'd share this...I had a sprint booster V2 on my NA for years and loved it. No matter what anyone says, the sprint booster improves the driving experience.
I had recently watched a YouTube video of a guy who tests the Chinese version of the Sprint Booster, called 9-Drive and has different no-name manufacturers.
Long story short...I ordered one of these. They are awesome and you can find them for $35-55 in different places. Just make sure you purchase the one for Mercedes. There are some that are sold for Chryslers and they list the Crossfire but it will NOT fit.
I ordered mine from Alibaba Express for $32. Here is the link:

You can also order one from Amazon here:

They essentially have three different settings with 9 levels each. Normal throttle response (stock), Improved Driving and Racing. Each come with 9 different levels to tune the responsiveness exactly like the Sprint Booster V3 does but for a fraction of the cost.
I put one on my SRT6 and it's amazing what a difference it makes. Fun to mess around with the different settings and finding the one you best like.
Only downside is since they ship from China it take 3-4 weeks to receive. There are many videos on YouTube from people who bought them and how they liked them.
Just ask if you have any questions about it.
