C32 AMG
Anyone used www.SpeedTuningUSA.com
I noticed www.SpeedTuningUSA.com sell a ECU chip for C32AMG quite cheap, $325 for ECU upgrade. The power figures are stock hp/trq 354/ 450 to 376 / 485. Which is same as Powerchip/Evo, etc....
I've tried to ask where they get their software from with no luck. Not sure if they develop their own or source elsewhere.
Has anyone heard of these guys and if they are reputable?

IIRC, the Kleemann ECU chip is nicely priced as well - don't recall how optimistic the hp/tq gains are though. The pricing information I have from them (end of last year) has the boost kit and ecu combined, so not sure about it by itself.
Boost Kit and ECU upgrade $3,395.00 (+40 HP, +45TQ)
Which is the one I'm going with after warranty expires in a few months. I'm pretty sure I've seen others on the board here comment on a ECU-only solution from Kleemann as well. You FedEx your ECU to them and they reprogram it - if you add other Kleemann things to your setup, you resend the ECU to them (for instance, cams, etc...).

No one has posted any gains from a dyno with their software. I had their software on my old C320 motor and I had it dynoed. Lost 10hp and the rev limiter was LOWERED to 6000 rpm instead of 6500 rpm stock form. Paid $350. 
I'll post the dyno. IMO, ECU tuning doesn't work since today's stock ECU software is so complex. The ECU is constantly adjusting fuel, etc all the time. I'll mod any game console before I mess with my $1400 ECU.
....waste of money

so you did a before and after dyno? what were the conditions? same dyno? same temps? same fuel? just curious what the controls were for testing the product?

thats the only reason I would use powerchip, cuz they are local. I can easily take dyno baselines with pulley and with pulley and ECU.
sending my chip to kleeman and mix and matching my EvoSport ODPS with their tuning is probably not the way to go.
However $350 for speedtuning, it probably is worth the hassle.
I might end up taking it to powerchip with conditions that if they don't produce at least 15 RWHP, I will want my stock settings returned.
I rather spend $1k on my SL55 splitter, plus and wires and Speedtuning ECU.

i agree, especially with the last thing you said, i am trying to get the best bang for my buck, but i don't want to throw money away on products that don't work, i would rather pay more knowing that i am definitely getting something instead of hoping i am...
that is why i would like to see someone post up some test results where there is some kind of control within the testing...i want all the data, not just some dyno pulls, you can make a dyno say anything you want inorder to sell a product, i have seen it happen right before my eyes...

Ask AMGSC if his SpeedtuningUSA software made any gains on his HPS gen2 C55 after 3 weeks of "road tuning." 
He has plenty of dyno pulls, over 200 I heard.

This speed tuning USA have a physical location or is it a residence? Do they have a dynometer for on site tests? Do they re-flash ecu or are they still de-soldering the chip? Who is the individual that does the actual tuning? How many years has he been actively tuning ecu's?
For $325.00 I would be scarred to see my results. Wonder why the competition charges over 1k. If this is the person that I'm thinking of he has already put one car at the dealer with an improperly tuned ecu. Price to fix 40k. Hell of a way to spend $325.00. Be cautious, do some research.

I have the Evo pulleys and the speedtuningusa ECU flash on my C32. I have had them both for 4 years now with no problems. The car traps in the 112mph range at the 1/4 so it is making the power. Just like anyones ECU it will require better than 91 octane to get the full benefit.

that is good to know.. i'm thinking of going this route...
do you have any of your old time slips around?
or any dynos during your tunning?
I'm going to call them on Monday to start the looking into it.

all you know is that SOMETHING is making power, which could be the pullies only. your speedtuning chip might be making you lose some, in which case your trap might be even higher. though 112mph is rather high, i just thought id bring that to your attention.

I did the speed tuning ECU upgrade on my C320. Definitely gained at least 15-20HP. Feels strong although have not DYNO'd the car yet.
Blackbenz (CLK430) and BJ also (CLK430) also chipped their cars the same day. All of us noticed the power but we are curious of the exact proclaimed gains.
All in all I recommend it, for the price can't beat it.

Thanks for the input guys, it sounds like it's a case of, you get what you pay for.
The $350 is definately cheap but I'm not convinced by the results, actually far from it. There's are a few "not so good" reports around from bad experiences.
Might be worth spending the extra $$$$, if not for performance, for peace of mind.

If any of you decide to get the ECU flashed with SpeedtuningUSA, get it dynoed first. I will even give you a free dyno coupon that I won at the last Octoberfest get-together in Irvine. The coupon is good for one free dyno with air fuel monitoring. Then you need to get a dyno after the ECU flash. We need to put an end to this "Oh, I think it feels faster. My butt dyno says it's faster." Rest assured, you will not see any cooked dynos at HOP.

Ive also been wondering around this, and thaught of doing before / after dynos just to see if it works, remember for those of you trying this that like with EVERY mod you do on these cars, the ECU needs a couple hundrerd miles of driving to fully adapt to this software, then is when the dyno pulls should be done.
Although, for piece of mind I might use powerchip, and THEY DID assure me I could send my ecu back to them in case of any extra mod i would add to my car...example, cams... etc.
