CLK500 Upgraded with Speedtuning USA ECU




I have officially joined the group buy!

I just updated the GB thread in the GB forum and I left a few questions there. If you have a chance, take a look and tell me what you think.
Thanks
Jason1000RR,
They sure have, but for the worse!

I've been having so much fun with my new added performance, , that I get on it every-single-chance I get!

One difference I can describe is when I do an aggressive right hand turns. Before, I make the turn, hit the gas, and then the car would bog down then go.
Now, I make the turn, hit the gas, and the car just goes!

From all the mods that I've done, this has to be the best (and I've done a lot of mods). $300 is really not a lot for what you are getting.
Once I calm down and drive somewhat normally, I'll update this thread with my new gas mileage readings.

Let me know if you have any other questions.
Also, it was mentioned earlier that the stage 2 is a 30 hp gain. Does that mean I'd have to change the pulley to get that much gain? How much gain for just the chip?
Thanks.
Steve

Shoot them an email, they are pretty fast in responding. They will answer all your questions.
335i is a turbo engine which can be easily increased boost to increased hp to how ever high the turbo design to run. The Clk 500 is a n/a engine which is alot harder to increase hp throught ECU upgrade. It hard to tell if any increase in hp without dyno. I'm sure you will feel the car response much better through ECU mods the wire drive by throttle like the spring booster.

If those don't work for you then TVT Design is located in Nj and I think they tune also.
Mercedes will not be able to detect the tune, so we are safe.
Stage 2 is around 30hp and 40+ TQ thats if you have N&N and 2nd cat delete or highflow 2nd cat.
They told me we can do a group buy if we get 10 people it will come out to $359 per person clk550 and clk500. and $260 for the clk350
