Hey Guys! Recently upgraded my Powerchip Tune to a Weistec Tune. Right when I left Weistec I already felt gains from my recent tune. I worked with Matt @ Weistec.

Powerchip Tune was alright. Car became noticeably faster from stock. I was satisfied with it but I knew there were tunes out there that could do better.

I ran my friend Saeedg48's cls63 stock with my PC tune and i was surprised on how far he pulled on me. We both thought my C63 was really fast til he got his CLS.
After he got his tune i ran him again and now he was Bus lengths ahead of me.

This is when i thought to myself i need a better tune. Did my research and I went with weistec.
Everyone at weistec treated me well and they are great people who work very hard to do the right things.

you'd expect the CLS to be that fast for the price is has It's the same price range as the GTR, it only makes sense to be as fast.

Glad your enjoying your new tune.
Not really an apple to apple comparison with the CLS63.
Would be better if you did a before and after run with a car with similar power.

CLS is a beast. 400lbs more too and just walks.

Fung63

those are pretty decent numbers you got from the tune.

Great videos and great chioce tuning with Wesitec.

Btw, The CLS63 will surly beat you in all RPM ranges, but you are giving it far more advantage when you both are launching from low speeds. Remember this is a tuned CLS, the torque on this baby far exceeds the torque numbers on your car, which will help in launching. Try racing side by side from 50mph~60mph and lets see how much he is able to put you behind.

Our runs are done to see how much faster the cls is compared to the C. And to see comparison of how it can keep up with 2 different tunes

these new v8 bi-turbo's do NOT **** around.

OP be safe out there dude.

The CLS will be be faster, regardless of what tune the C63 has.
Personally, Id run a C63 with a Powerchip tune + 2ndary cat delete for comparison.
