C43
Have been looking at this tune as well in my search for the perfect piggyback or ecu, but it seems steep for the gains honestly! Look forward to hearing otherwise, because between the Kleeman, Weistec, or RennTech, im curious to know about others outside of the JB4 world...
But as of now, leaning towards JB4 because everyone says too

I know my car pops A BIT on down shifts and when lifting off, but its never more than 3-4 max if you're really trying. This is just ridiculous and it sounds **** imo. And not suited to a supposedly smart German performance car.

I have heard that car. I don’t think it’s the tune sounding like that. If they sold me that I would be calling lawyer again. He put blow off valves on the car. I think the car sounds stupid. Rennet has told me tune is the same as 18 cars. No change. They said car will run good with noticeable improvement. I hear a lot of bad stories on here with AMR and I think Eurocharged is pushing car to hard. JB4 not for me. Always issues and not making the power. Audi guys having simlilar issues on their side as well.

Exactly how I feel. I got the PE and think it's perfect for the car. I don't know why anyone would want to mess with it, but that's why we have options. I know he seems happy with it, so in the end that's all that matters. Not for me though lol.
