Carlsson Tuning ECU for CLA250 and CLA45AMG - 450hp!
This is a discussion on Carlsson Tuning ECU for CLA250 and CLA45AMG - 450hp! within the CLA General Discussion forums, part of the Mercedes-Benz CLA Forum category; "For the CLA250, those numbers are boosted to 253 HP (186 kW) and 420 Nm (309 lb-ft) of torque - an increase of 42 HP ...
There's no way they are getting an extra 90 horsepower out of the cla 45AMG that engine without additional modifications

According to the "Auto Evolution" link they say, "From what we can tell from the official press release, Carlsson simply installed a version of the Carlsson C-Tronic CB Plug & Drive module instead of the original ECU, making the all-wheel drive AMG version of the baby-CLS to develop no less than 450 hp."
Look, back in the '80s, BMW was famous for building some 4 cylinder engines that made ridiculous amounts of power for their Formula 1 cars. They had 1.5l engines that were putting out anywhere between 1,000 and 1,400hp (depending upon how much boost was dialed in).
I don't doubt that a tuner can find more horsepower from the engine. My primary concern, however, is about long (and, in this case, even short) term reliability. The turbo is already spun up to make 26lbs of boost. How much more pressure do they need to extract another 90hp from the stock internals? And, can they take it over 100K+ miles without serious modifications? Just because you can do it doesn't mean you should.
A stock 335i isn't making 26psi of boost out of the factory. I'd venture a guess it's closer to 14-15psi. Someone with more knowledge can confirm or correct me.
