This one sounds fishy. No details aside from a claimed ecu upgrade.

Not sure what to think as Carlsson is generally considered a serious/dependable tuner.

Wow! That's crazy. Just what I was waiting for...an extra 60 hp is perfect. It's gonna be a little rocket now!

If this car A45 or CLA45 get 450hp it sure will be rocket.

Cant wait to see this car.

90 added hp from ECU upgrade? WOW

Well it's really a 60 hp jump from the ECU because Renntech already dyno'd it at 390 hp.

The engine is already seeing 26psi of boost.
What's the turbo doing now?!

-Eric

My thoughts too. There is a point in which you are asking too much from a street car's engine. I would say 225hp/L is way past prudent.

But hey, I don't have to pay for the repairs - go for it!

Their claims are usually highly over rated. It's probably 420-430hp tops in real life

That's enough for me.

Did I miss something? the cla45 actually has 390hp not 360?

Yes, unofficially

wow that great

Good ol' MB. Underestimating as usual.

In all seriousness though....mother of God....

450 from a TUNE??? Not including a possible improvement on downpipe/intake/cooling??? Evo & Sti guys are going to be *PISSED*...

These modules are available through GMP Performance

How much are the modules?

That's insane. Just kind of worried about the boost pressure

Kind of worried? A guy in Taiwan on Mercedescla.org installed a tune and is now searching for a new engine. He doesn't even have a 45 which as we all know makes 26psi stock! That's insane from the factory. How much more pressure can the engine take for an extended period without impacting long term reliability?

-Eric

Yup. That is why i wouldn't tune the engine. I think it's hard to talk yourself into a new engine covered by warranty

Carlsson back their products with a 3-year/30,000 mile warranty on their tunes & products, including this car.

It's quite simple. Get a tune from a company with a reliable history. The only reason to be scared is if you don't know what you're doing, in which case, DON'T DO ANYTHING.


Seriously, it's not hard. Mercedes/AMG isn't going to build an engine like this without leaving play room for safety purposes and for warranty reasons too. Longevity is expected out of these cars from their buyers. It makes no sense to push an engine to the limits of it's stress management immediately.

Same rules have applied to all their other cars. I'd bet my soon-to-be engine this car is no different.

There is no longterm reliable replacement for displacement. Sucked, blown, stroked, or juiced all motors take a toll from having an un-naturally aspirated intake or raised compression to increase the power generated during combustion. There's a price to pay for smaller lighter weight power. I'm sure the engineers at AMG have produced as much power as the engine can safely handle for the lifetime of the car. Any increase to their limit will definitely shorten it's lifespan. The more power you pull out of it the more stress it places on it. So you may not pop or melt it with a 40 hp boost, but over time it will break it down faster. That's the reason I won't buy used semi-performance vehicles. There's people out there who will perform ECM changes along with other mechanical aspects and then return it to stock at the end of their lease or when trading in. I don't get rid of my vehicles until there's at least 100k on the clock and if the first 36 of them were ran like a raped ape I don't think I'd get past 70 without some failure.
I only tune my bikes because I can easily afford a rebuild or replacement if I push them too much. I'd hate to find out the cost to replace an AMG engine because I wanted to shave a few tenths off a quarter mile. I'll save that for a non-daily driver with a cage or a wheelie bar.
Trust what the Carlson or Dinan or whomever performance company says, maybe it'll last for the duration you own the car. But I guarantee it is detrimental to the longevity of the engine/drivetrain, and good luck to anyone with a warranty other than the original manufacturers when it comes to bolt on or tuned in performance. It may get handled, but not without a hassle.

Please point me to a Carlsson warranty that clearly applies to products sold in the United States that is subject to US laws and jurisdiction -- not just products sold/installed by Carlsson in the EU and Switzerland that is subject to the German Civil Code and Commercial Courts.

I'll be here all week.

And no, it doesn't say or implies that said warranty is limited to any country. Problem is no one ever wants to shell out the cash to actually do it right.

There is no warranty at the link you provided. You provided a link to a marketing piece on the CLA that says their parts have a 3yr warranty. Show me the actually warranty. BMW says it offers a 4yr/48mos new car warranty...but that statement isn't the warranty smart guy.

-Eric

Quoted from said page:

"Carlsson offers a three-year warranty on all their conversions and parts. With fitting done by an accredited specialist workshop, the factory warranty is unaffected, and Carlsson guarantees all its own parts in full."

You want a warranty contract? Contact Carlsson. I've got better things to do with my time.

How big of them! But Carlsson cannot tell you that the factory warranty is unaffected. They have no authority to tell you whether Mercedes believes Carlsson's product voids a portion of the Mercedes warranty. Get something in writing from MB that it doesn't void your warranty or have Carlsson show you a full car warranty in the US under US law in the event MB elects not to cover a claim against an MB warranty.

I'm not going to give you a primer on common law vs. civil law and I can't help it if you don't understand how contracts work. All I'm telling you is that your expectations are off and your understanding is wrong.
