Apples to Oranges.
Also a different type of dyno - which is totally not accurate to compare.
I am all for good data, but let's be fair and even handed!
Thanks

At $6K for ~14 HP it would seem to be the lowest bang-for-the-buck RENNTech mod. Does look nice, though. How does the car sound with the Eisenmann exhaust? Does that come in after the stock cats, or are there other mods to the exhaust system on your car? I just got an '04 SL600 (haven't seen or driven it yet; I take delivery Monday). Given my past experience with RENNtech magic I am looking forward to having them mod this car so I will have an "All RENNtech" garage. Thanx for any comments.

As an automotive journalist, let me suggest the following:
To be truly scientific, you need to take one car, dyno it stock, then do the Powerchip mod on 91 octane (which is what we get here in Calif) and then do the Renntech mod on the same car, equalizing temperature between runs (Brad of course knows this, as do most of you other tuner guys). Same dyno, same location, same car.
Then, publish the dyno results and the retail prices of both.
Both Powerchip and Renntech should eagerly offer up an off-the-shelf unit for comparison testing. If not, so long as they both agree to gimme my money back if they come out on the low end of the stick, I'll pony up.
It would also be nice to get a paragraph from Powerchip and Renntech on the "other" advantages of their ECU mod (i.e. maintains factory warranty, tuned as far as possible without affecting reliability, etc.)
I see posts like this on other baords all day long. Apple-to-Orange comparos are a disservice to those considering spending their cold hard cash on such a mod.

I will do the Powerchip and we have a dyno. I can serial program Mercedes with Powerchip, so we can do it here in the shop. We also have the factory diagnostic tools to monitor ingine paramaters and the dyno will give us Air/Fuel ratios.
Thanks

i have had oliver at speedtuning both of my cars for several years with no problems. he just did a upgrade to both cars, 03 55's. one had been just flashed at the dealer. both still are running great. he has recently done several e55's and a s65 locally. i would reccommend you contact him on the phone about the sl600. he has programs for any car gas or desiel.

New guy here. Just bought a 2003 cl600 and I'm considering mod options. Trying to discern whether the extra $3500 for Renntech over a Powerchip is really worth it, so I thought I'd revive this thread.
Any thoughts since September?
Thanks in advance.
