C63 Renntech Vs Weistec Tune?
I Just picked up a C63 last month and have just started to look into tuning options for the car. The two i have narrowed it down to are Renntech and Weistec. I have looked around on the forum and I have to say its really filled with great info but i really haven't been able to find anything on these two company's for tunes. Was just wondering if any members on here have any feed back on which on they feel will give me the best gains for the car
But i'm tempted by the flexibility of weistec. Will probably pull the trigger in a few months time when I will install headers.
Price wise Renntech is well known for being expensive.

Feel free to hit me up any time with any questions. We offer the handheld also.
Congrats on the new ride!

edit: I see the price of the RENNtech tune has gone down by $750. While high it's now a lot more reasonable IMO.

If you have a local or semi local shop that carries one of the tune, that would be the way to go if price is not in your equation. If there are issues, it is much easier to get help.
I had a Eurocharged tune C63 and Jerry has now tuned my CLS. No issues.

In your situation that's a tough call. I went with RENNtech because my SA was RENNtech-friendly. The store services a number of RENNtech-modified cars and apparently they've never had an issue. Like I said though, price matters too.
