This is what Renntech says about my car if you call and ask them. NOT GOOD.

I've had completely different experience when I talked to RennTech; all my questions have been answered, and as a matter of fact, they've been answered quite thoroughly and professionally. However, I have been mostly dealing with Ken, who has been by the way, extremely nice and absolutely first-class every time I talked to him. The few times that I did talk to Bob, he was very helpful although I did detect slight doubt and/or hesitation when other tuners were mentioned, but nothing disrespectful or demeaning at all as what went on in this case.
Honestly, the bashing game has been taking place from both sides, as I've read so many brief comments and "hints" taking shots at RennTech as well as other big tuners over the years. And I am not, by any means, suggesting that it is okay, but do realize that it does happen and happen often. In an internet world, word spreads fast and almost never spreads correctly making the truth harder to trace down.
One drawback about being the big and "expensive" company is that their screw-ups are spread very quickly and very publicly. While I've seen many "hush-hush" on multiple screw-ups from smaller companies.

So ok you have a car that is 1 mph faster in the quarter mile like for like. Hardly a place where you can get high and mighty. Your car is great and I will say its fast as snot but every comment around here is that RENNtech is junk. So explain how their car with an admitted 100 fewer hp at the wheels (in your eyes) is just 1 mph slower than your car?
2. Never said Renntch was junk. Where did you get that?
3. Show me the Renntech car with my weight trapping 129.
4. Torque management interferes to a greater extent the more power the car puts out. I haven't gotten to the track yet with my new TCU which is supposed to address that issue. I posted this above also.
5. The 700 RWHP shows up on a dyno. It is only viewed by "my eyes". My eyes have yet to create something that is not there.
Let's not forget......You brought up my cars performance and gauged it against Renntech. I didn't.

Over two months ago, VRUS/VRP posted:
In this thread:
https://mbworld.org/forums/w211-amg/...5-65-tcus.html
What happened? Have you just not had a chance to track the new VRP TCU yet, and see how many 10ths it actually shaves off? Do you not even have it yet, over two months later?
It's hard to gauge some of these advancements and their efficacy, especially when a lot of info is posted upfront, and then the subsequent data and results (good, bad, or otherwise) aren't followed up with...
As for the topic at hand, sounds like Renntech isn't immune to "salesy" salespeople on the payroll - but I tend to agree with CynCarvin, they make high-quality parts, albeit at a premium pricepoint. It does speak volumes that MBUSA picked them as one of only 4 tuners for the GLK PR move for its release. Can't recall offhand, who did the "Pikes Peak" themed GLK? That thing was a beast

I dont think you want to run Marko. Your car is fast though for an E55 but Marko has the big boy V12 biturbo and currently the fastest non nitrous MB. Just call out other E55's hehe

Great Experiences with RENNtech
I have had 4 AMG vehicles (E55, S65, and 2 CL65s) tuned by RENNtech and have had nothing but excellent results. They are top notch.
With respect to RENNtech's performance, in our usually hot, humid air in Florida, my personal cars have yet to be beat by any other same model AMG with the same mods on the same track, on the same day. I know there is no other CL65 going in the 10's in our Florida heat with only my mods.
I have nothing against any other tuner. I just have had excellent results with RENNtech.
With respect to RENNtech's business, there is never a shortage of cars in their shop waiting to be modified. That speaks volumes in this economy.
Everyone just needs to take a deep breath, and focus on more important things than the griping in this thread.

FWIW, the only time I've dealt with Renntech directly was to get a new set of lug bolts for my Monolite wheels - they were extremely friendly and helpful, even knowing that they were only selling me a set of lugs...
Your post is confusing in that you didn't really answer my question about the TCU - but it's OT for this thread anyway; I'll ask it in the appropriate spot.

Do they?
http://www.dragtimes.com/Mercedes-Be...ag-Racing.html
Also keep in mind that, despite what the Dragtimes slip says, that car has the OS Giken diff. ($4995 from RENN http://www.autofiends.com/index.php/...s-eight-grand/), not "stock", RENN's long-tube headers (not short), and the RENN mid-pipe ($2440 secondary cat-delete/"sound-performance pipe").
Don't get me wrong, RENN's little C is a MONSTER, I'm just pointing out facts about the car (seen here http://jalopnik.com/5168541/renntech...cr-first-drive) on the night it made that time.

Point of clarification. I drove RENNtech's C63 the night it went 11.50s. The car had short tube headers and cats. 100%.

When was the last time you've seen RENNTECH change their company name to avoid or hide from problems like so many others do Bottom line they have so many great techs and are well known through out.. Why so you think most new shops go after RennTechs hp #'s? With that said , I would say that some how RennTech makes most car fast even if they don't touch them, Just because everyone is always trying to make more power than them 
I've eve had my Renntech tuned ECU damaged when some one tried stealing thier info.... Yes there are SALES MAN out there that just don't get it but that shouldn't make a differance to you , you're not buying the Sales guy

Are you sure you read my post? Doesn't seem like it. You seem much more emotionally driven than factually.

Do you think it is appropriate for that kind of derogatory rant to come from a company with Renntech's credentials? Please address my questions.
Everyone on the Renntech bandwagon just comes in and either misquotes me, challenges my credibility or my car's performance. And on top of that I have been challenged to a race by a girl with a slower car.....
Do you people feel threatened? I never bashed Renntech, they bashed me and their supporters continue to do so.

This is not about Renntech as a company, more about Bob Brady... Hartmut knows his stuff, this one particular sales guy definitely does not and has a very arrogant attitude about products he knows very little about.

I know his car is capable of beating my car, that's a given. Why call out RENNtech for a comment your friend heard? I'm sure it pissed you off Marco but all tuners talk crap. Tell me who tuned your car and I'll post a story. Why post it in the E55 section? I got a bit fiesty on the call out, but i dont think its cool to bash a tuner based on a second hand comment.
Mike,
Yup, I'm still coming. You are on probation? LOL See you soon.

2. It pissed me off because it was lies, not talking crap, as you put it. Nice try to minimize it.
3. I tuned my car. Tell me a story.
4. I always post in this section.
5. I posted facts, not bashing.

Whatever we're tuning!
Marko-
You've been honest and upfront from the get go about what you are trying to accomplish with your car and with whom you are trying to accomplish it with.
Your car is EXTREMELY IMPRESSIVE and the facts are:1) the amount of time(R&D), 2)money and 3)a platform that, god forbid something goes wrong, the cost to fix your engine is HUGE. You should be commended for what you have done.
That being said take what the haters and nay sayers are saying and just realize that it comes down to jealousy and just plain HATING!!
Keep raising the bar for all of us in the tuning business and let all the BS just roll off your back.
Stick and stones can break my bones...........you know the rest!

Marko I think it might be time to head down to Florida.
SGC do you think the RennTech C63 is faster than the MBK car?
Bottom line is Bob Brady needs to come here and clarify. Obviously Marko has respect for Renntech as he has stated this numerous time. He is upset that someone from Renntech made statements about his personal vehicle. It is a slam against him as he is a hands on owner.
So Bob Brady needs to make some comments here to put this thread to bed.
