Please send me as many details on your car and dyno as you can.
Your baseline is a bit low. I need:
1. Dyno graph with A/F
2. How many fans did the dyno have?
3. How many miles on the car?
4. Stock air filters?
Thank you!

2. One large fan
3. 14,000 miles
4. Yes, stock air filters. I wanted a set of VRP ones but was told only if I bought an airbox, which I did for my E55. Victor said he'd get me a set for my SLK55, but I just traded that for this SL.

Now back to your dyno. It actually looks pretty good. The reason your numbers are less is because you were on a DynoDynamics dyno. This will read about ~10-15% lower. You just need to throw the car on a dynojet so you can do an apples to apples comparison. Hope that helps.

I agree, regardless of dyno type if you did before and after runs the delta-difference is what matters, the car should have picked up more power imho. What pulley size do you have the asp equivalent or the smaller ?

No we didn't. It's the stock system with just the johnson pump added. My after dynos were all very consistent, unless they were all consistently heat soaked. I suppose that's possible. There was some air in the system which I got taken care of now(I think). I have a dyno on a dynojet scheduled for tomorrow. I put a bunch miles on the new ECU whereas before it was fresh off the truck, we'll see how it turns out. It's the same dyno my brand new stock E55 turned out a staggering 398.6 on.

Robert,
You need to give the ECU some time to adapt so make sure you put 150 - 200miles on it before you dyno. Doing the dyno right away after the install was mainly to make sure nothing went really wrong and to check on your A/F.
You will notice the car will get stronger and stronger as you put more mileage on it.

I'm also curious about the baseline. I always say not to get hung up on the actual numbers, but on the curve itself. The difference in mine is stunning. It is NOT subtle and can in no way be ignored. Assuming you got the same tune I did, I just don't see why you wouldn't get similar butt dyno results.
Another thing for everyone to keep in mind is that not all deltas are comparable, either. It isn't a linear relationship. If all you really care about is seeing a number (ahem, charles), then just run from dyno to dyno until you get a number you like. It literally means nothing. I'd personally look at the dyno graph and compare the curves and A/F ratios to other 55s. That should show you where the shape of the curve has changed AND what the A/F is up to.
I just ordered a new datalogger. I had gotten the old one from Sears for about $200. It is a great way to see how the car is acting in the real world. I know that Vadim gathered a butt load of data on my car as they worked the tune.

What gear was that run in? Why does the before Dyno not hit the limiter?
The curves look really good to me. The only odd one I see is the last one. The A/F/ seems to dump to below 11 in mid range and then picks back up and dumps to below 11 at the top. The other curves look good, so it may have just been a run anomoly.

I've put a good hard 300 miles on it, the trip back to Dallas was 230 miles by itself. I was running it pretty hard the whole way back. Really really hard for about 50 miles when a CLK63 came up behind me. We were both going the same way so we figured lets have some fun. Hit the speed limiter a ton of times and generally zipped by the slowpokes chasing each other at 120-140. Then when 2 lanes would open line up and floor it. Unfortunatly the CLK63 ate my lunch quite a few times, he always seemed to get the jump on me but I was able to keep him from gaining any more. I pulled away a few times at lower speeds but he had me at higher ones.

Oh yes. I am planning to mod this thing a bit more before I just start commuting in it. The only reason I waited for now is to give Vadim and Powerchip a chance to finally stir up the technical pot. There is still a great deal of unknowns about these cars and its nice to see a tuner step up and be willing to go into that darkness. One thing I would remind any first timers on. Modding a car is not always the easiest thing and things can go wrong at times. The key is how your tuner treats you, your car, and the situation. I was ready to do pulley, TB, headers all at once, but wanted to give Vadim the platform to do his thing. It may take me a bit longer to get the right mods on the car, but in the end it will be a much more refined tune than if I had done it myself.

The green run that dropped below 11 was actually the middle run, look at the file names.

Well, then there is one issue. You need to dyno in 4th to keep it consistent. 4th gear is as close to a 1:1 ratio that we have.

Im a Vrp 530 so it would be Vrp on Vrp crime.. Course I do have the Evotech ECU.....
I wish we had a track day to attend. Everyone seems to be bailing on Sacramento, Fontana is over and Speedworld is 5 hours away. Irwindale is every Thursday but it is only 1/8th mile.
Its great that you can be hands on and see the progress, wonder how much you have picked up??
My times improved 1/10th adding the pulley, moving the IAT sensor, and adding the spacers. from 12.40's to 12.30's trap speeds are yup maybe 1/2 mph.
Here is Chiromikeys run

He had me just about every time. The limiter is what kept him from getting away, he was usually 2+ cars ahead of me when we hit it.

That isn't right. They should be fairly close if both are stock. the 63 breathes a little better up top and the 55 has a little more grunt down low, but all in all they are VERY close. Now, having done the mods you have, you should be spanking a 63. Maybe not mutilation, but a steady pull every time would be expected. Again, it may be the driver getting the jump on you. No disrespect intended, but jumps count for much more than raw power.
