Kleeman ECU tune, 3.5L C300

Lol sorry it's just I've read through this thread, every single post, and there is nothing but a circle jerk questioning not only the validity of posters claiming HP gains, but also calling out specific tuners who also say they don't wish to comment further while providing NO FACTS. This has in turn led to speculation, name calling, and other kiddy petty behavior that would be better suited for a Volkswagen forum.
Seriously read all the posts and see if you come out with any real information, there is none.

Kleemann updated their website. Kleemann headquarters is straight up claiming that the M276 engines in the C300 and C350 are identical, and listing the tunes as having identical gains.
Before, we only had speculation and a couple of emails. There was a lot of controversy because OE tuning claimed that the engines were mechanically different. They sent me a cease and desist via PM when I called them out to prove it. I'm really hoping that with these new claims that they have dynos to back it up.
I guess this is either another baseless claim, or OE tuning was false in their claim that the engines were mechanically different.

The latest generation normally aspirated, direct injected, 3.5 liter M276 V6 engine, with a maximum of 306 HP and 370Nm (272 lb-ft) of torque, is a powerful and smooth mid range engine. This engine is available in the 2012+ C, CLS, E, and ML. Our R&D department has spent an enormous amount of time perfecting the ECU software for this engine. An increase in power of up to 330 HP and 400 Nm (296 lb-ft), as well as improved throttle response and raised speed limiter, is now available. As a unique KLEEMANN feature, we have managed to improve the software in the 300 models (which is, in fact, the same engine as the 350, but intentionally limited in power production by the factory) so the new power level becomes the same level as the 350, plus tuning gains. 300 owners will gain what is a normally unheard of improvement in power and torque from an ECU tuning.
300-K1(BE): ECU tuning. Up to 330 HP and 400 Nm (296 lb-ft) of torque.
350-K1(BE): ECU tuning. Up to 330 HP and 400 Nm (296 lb-ft) of torque.
300-K1(BE): ECU tuning. Up to 330 HP and 400 Nm (296 lb-ft) of torque.
350-K1(BE): ECU tuning. Up to 330 HP and 400 Nm (296 lb-ft) of torque.

question is, kleeman claims you get 330 HP and somebody pays for the ecu tune and somebody DYNO their car afterwards and its not 330 HP. Do you get your money back? They should also pay for the dyno fee as well :P

Not likely. Almost every tuner claims "up to xx horsepower" instead of "at least xx horsepower". In the best case scenario, with one of their technicians on the dyno, with correct fuel, air density, engine health, etc. you might get 330HP.

AWD dynos are not hard to find... Is there any other reason why someone with this tune and 4matic hasn't spent sub $100 to do a couple pulls at a speed shop somewhere?
Hell, could we start a fund and all chip in $5 to pay for said person to dyno their car for proof?

Stop talking sense... the tuning company themselves don't even want to dyno it...

I guess I am wondering, if I pony up a before and after dyno (there's a mustang dyno 15 minutes from my house) and the results aren't even half of what's claimed is a refund in order? Or half price on the tune?
Because having my brand new car down a week better account for something...

I got email from Cory:
Hello Roger-
Thanks for writing!
We do offer an ECU tune for the M272 V6 engine found in your C300. The price is $795.00 and gains are typically +20-25 HP/TQ, improved throttle response and we remove the top speed limiter.
If you have any other questions, don’t hesitate to let me know.
Thanks again!

OK it has been done. I took my stock 2013 c300 to the AWD DYNO and ran a baseline. Cory will be getting my ECU next week and i will post before and after test results for the tune. This should put an end to all the back and forth. Im hoping the test shows it blows the horse power up.
ps. baseline showed 253.7hp at engine 220.6 at the wheels

It may be important to note, i also did the magna flow x-pipe and resonator deletes. it sounds better, but i don't believe it actually helped any as the stock exhaust is pretty dialed in.
