Finally with the nice weather I decided to get the CLA45 out of the garage. Man I missed this car, so much fun on the back roads. Well I am going to get the Weistec tune and do a review on that so I am selling my Renntech tune which I was very pleased with. Really increases the power nicely, I want to do a review of the Westec tune though and compare it to a piggyback. PM me an offer.

I will also be going with the weistec turbo upgrade when it comes out!

Liking the sound of this. It'll be nice to get your unbiased feedback on the Weistec ECU tune. Reliability is my primary concern considering it will without a doubt void the factory warranty. Keep us posted.

When I got the TCU updated at the dealership, they didn't say a thing about the tune or downpipe. Frankly, I don't think they care, but it depends from dealer to dealer, really.

So long as the problem isn't a direct cause, I doubt it would cause any trouble, regardless of the company. Now as for the turbo upgrade? That makes me nervous.

How do you "sell" a tune? Isn't it resident on your ecu as programming code?

Piggyback, most likely.

I'll be following your feedback from Weistec tune.

Just got my Weistec tune with the bypass valve will be installing on saturday. For anyone wanting my Renntech tune ill sell it for 700

is this the piggy back you selling? If yes can i get ỷr phone n.umber?
