Wondering if anyone has any experience or feedback on the ECU Tune that Weistec engineering offers? I read there ad recently which stated that the tune gives the C43, 400 Wtq which seems like a good number. I have not read of any board member having a Weistec Tune.

Thanks for any feedback in advance

im guessing their tune is a rebranded file from someone else, but I could be wrong. They are a good outfit and make some nice products. There are plenty of options for a tune on your car. Dinan has a new one out that maintains your warranty, AMR and OE are out there as well. Plenty of options.

Yes, I understand Weistec describes themselves as an engineering company so maybe it is their own version?

Also you forgot to mention Renntech & Euro Charged. I am definitely looking into Euro Charged as there numbers are great and its only $999.

I looked into Weistec when considering tunes, but after speaking with them I was not too confident in choosing them. The sales guy Mo sounded like he was stoned and he would forget to send me information and then when I would call, he wouldn't remember who I was or what he supposed to send me. All in all a poor experience and I think they should stick to their parts. I ended up going with AMR Performance for my tune and I couldn't be happier. I spoke with Matt over there and he was more than pleasurable to deal with. I highly recommend looking into them

I have had the Weistec tune in my CLS63 for about 5 months, The results were pretty impressive. I ran a 11.657 RWD, street (all season) tires, at 5800 feet altitude. (9,000 ft DA) I had a issue with a plug fouling, not sure it was related, possibly could have been. I do agree with the comment that Weistec has less than stellar customer service skills, it seems you e-mail, then wait days, then e-mail and finally get a response. I did ship my ECU to them and it arrived back 3 days later, plugged it in and the difference was very noticeable. The price difference between them and Renn-Tech is considerable. The local MB authorized dealer here in town sells Weistec and are big supporters of it.

Well this is my dream car hopefully when it arrives monday or tuesday its in good shape. Matt comes pretty highly recommended and hoping it will be noticeable i might do down pipes if its easily reversible just in case for smog. I really want to get to about 625-650ish rwhp.

You have 6 years from the date of sale of any new car in CA to enjoy down pipes. If you are wanting 600whp are you doing turbo upgrades? Matt at AMR is awesome. He helped me every step of the way.

From the info i got i should be about 600whp just from a tune give or take. I think with downpipes and tune that should not be a problem on a 2013 but who knows.
