I might have to dyno my car as well just to see what i'll put down on CSL headers, 200 cell cats and pulleys along with ESS tune.

Normal price is $500, the group buy price was $400.

No real down sides, I haven't checked mileage yet but a tune will usually increase mileage if anything. I did leave the revlimiter stock since the S54, with stock internals, is out of breath by 8k as is. Increasing the limiter beyond that on a motor that's already revving pretty high for having such a long stroke could potentially reduce the OEM rods' lifespan, but I have no proof to back this up, just a gut feeling.

Mr. Wolfe
Your review helped convince me to try ESS out. SS stepped V2 w/ a CRT will be the next mod down the road. I'll dyno that as well.

Do you have AFR results for the middle graph? It would be fun to see those as well.

I'm glad to help spend your money. Anxious to see your results after the headers.

Jonathan, great results. We will have to get together when my brother comes to visit. I would love to see some friendly pulls against his stock car and yours.

Unfortunately not really, as mentioned above, I did take AFR readings but the wideband at the shop couldn't seem to pick up a good reading. Its tough sometimes to get a decent reading after the exhaust gases have passed through the cats and entire exhaust system. They even replaced the sniffer and hose in the time between my baseline and tune dynos since it was so off. The AFRs with the tune were actually richer than baseline, but still off from where they should be. A tune will usually lean out the AFR to make power, if anything.


All I have with me are the AFRs from the baseline pulls:

Thanks. I missed your notes above, sorry about that.
Agreed, usually the aftermarket tunes will lean it up. The AFRs I had with the ESS tune showed a leaner mix than with the Shark tune.

Thanks, Ralph! I'm currently living in New Orleans for work, but I can't wait to move back to the DFW area. I'd love to see Aaron's E46 sometime.

Thanks for chiming in Roman,

Any possibility of a 2011 group buy? Very interested, as I know the CSL option has a higher charge.
