Beware of Kleemann

Beware of Kleemann
The staff at Kleemann are super nice, especially Cory. That is the good news, The bad news is that you can not believe what is on the web site. I purchased a Kleemann supercharger for my 2014 C 63 at a cost of over $11,000. Instead of the advertised gain of a minimum 162 lb of torque, my car gained 75 lbs. Instead of the advertised minimum gain of 155 hp, my car gained 100hp. I have complained to the Better Business Bureau and soon to the FTC for false advertising.----Nice people, even a nice looking product--it just does not produce the desired performance that you are buying.----STAY AWAY--FAR AWAY

The tuning and install was by ACG in San Diego, an extremely professional concern. They have had lots of experience with both firms and I wanted Kleemann because of the advertised performance, my mistake. ACG is a great tuner and I would recommend them highly, it was not their fault Kleemann's supercharger is not what is advertised.

I am not very good with down loading to web sites, but I will try to post before and after Dynos. I have two of before and after tests,--- one with a Mustang Dyno and the other with a Dynojet. This is not the first time I have altered a stock car, and would never do it without proper documentation on both sides.--if I can't post today, my daughter will help me tonight (great to be young today)

Like others have mentioned kleeman advertises crank HP/TQ numbers, dynos are at the wheels.
I have used kleeman ecu upgrades for both my C63 and GLA 45 AMG and have always met or exceeded there numbers. Those gains at the wheels seem about right for the advertised crank numbers.
Do your research and understand how tuning and dynos work before slamming someone.

First, thank you very much for the kind words Steve! It's always been a pleasure working with you on the car
The car in question, for everyone's information is a 2014 C63 507 Edition.
We started with the car bone stock and added the Kleemann Supercharger system. Really good looking kit, in fact, installed it almost looks completely OEM.
Baseline, this car put down a very (and I mean VERY) impressive baseline number. It was however backed up twice so that's where we started.
The car currently has ROW Airboxes, Weistec filters, the Kleemann blower with Kleemann's tune file. Hits a healthy 5-6 PSI throughout the entire power band and 11.7:1 AFR. Very healthy indeed.
It's a very fun car to drive, easily walks my personal car which is a Weistec tuned '12 C63 with ROW boxes and Weistec filters.
I think Steve and myself will both agree the car is very fast and a joy to drive around town. I just know personally he feels that the advertised minimum gains are not being met, and that is a very tough pill to swallow when decide to spend the amount of money he has to upgrade his car, as any of us would be.
The next logical step of course is to remove the restrictive exhaust flow and we may very well do that in the near future if and when he is ready.

none... for now
You're using two different kinds of dynos, trying to say it's apples to apples, and are complaining to the BBB?
Your panties. They are bunching...
I'd also like to see these supposed claims. I've only ever seen "up to" claims by manufacturers, to avoid situations like this.

I've got to ask if you brought your concerns to Cory before announcing it here? I suspect he could have either explained "why" or recognized there was a problem & would fix it.
As others have mentioned, you're probably taking it too far, but knock yourself out. I've had Kleemann mods on 2 different AMG's now & your warning won't scare me off. Also, their advertising is done by the Denmark HQ, I don't see the FTC caring too much about it.
I am interested in the cost of the supercharger though; it's listed on their website at around 15k. If you got one for "over" 11k (but less than 12k?), I might have to email Cory. If you're really unhappy with yours, do you want to sell it at a loss?

First off were baseline and post blower dyno runs done on the same dyno? Regardless of whether its crank or at the wheels the 155hp is not being hit unless you are using a 50% driveline loss.....car should have gained at least 125whp which would equate to an approximate 20% driveline loss, and with my experience on these cars the actual driveline loss is closer to 18% with factory wheels and tires.

I suggest you take your car back to wherever you did you stock baseline and see what kind of numbers you get with the blower.

Wait...disregard part of my previous post. You did your baseline and post mod dyno pulls on seperate dynos??? Bro, you don't have a leg to stand on. Mustang and Dynojet dynos read completely differently. There is no way to accuratly gauge net gains if you are using to different dynos let alone two different brands/models.

We did pre and post dyno's here at the shop on our mustang. Steve also took it to another dyno in OC where he also ran the car stock before we did the work and drove back up to see how it performed afterwards as well. So he does in fact have pre and post numbers on 2 different dyno's.
On our Mustang he put down 390 whp and 370 wtq. He ended up gaining 80 whp, and 80 wtq. I can't for certain remember the other dyno numbers unfortunately off the top of my head but he can chime in if he wants.
Hope that clears that up.

Thanks for clearly explaining the situation. I'm sure the OP is flustered, but he left half the story to the imagination, and the other half vaguely explained.
So, even knowing that Mustang dyno's can be serious heart breakers, 507 at the crank and 390 at the wheels sounds awfully low, 23% loss in fact for those that hate math.
None the less, that does give a baseline. Add 80whp and we're at 470whp. 470/.77 is 610 at the crank. Indeed a 100hp gain. 100hp for that motor should be all of 3psi honestly.
I know you have no control over it, it just sounds like he's jumping the gun here a bit... of course maybe he did talk to Kleeman and just didn't explain that. Did the dyno runs come out perfect? Not that their should be, but any possible belt slip?
