Renntech Mods
I'm about to go for the ECU,TCU and intercooler mods on my SL600. The dealer and Renntech, for that matter, are really pushing the carbon fiber airbox. At this point , I just don't see it.

what you need to do
Is make sure that you do a before and after dyno. Make sure that you take it to the same place and try to do it around the same time of day.
Regardless of which tuner you choose this is a MUST have.

Why do a dyno before and after?
SLK55, do you think that they wouldn't give their best effort or they're trying to rip you off?

I think the reason for a before and after is for a few reason... one is the integrity of the shop, just to make sure you actually get the tune, but also to see your gains and to see if you have any other issues that you may need addressed such as your A/F and also your power band.

dyno
My reasoning for doing before and after dyno is actually very simple.
I want to know the modification I just did is working right and making additional HP (if that was the intent). As such it should also be inline with what the manufacturer says it will do (plus minus a couple percent is fine).
The ECU tune provided by the tuners is a good baseline. But they don't take into account all the different modifications that an owner will do. I like to do the dyno's so I can get the ECU fine tuned for every single mod that I throw on the car. (and yes my ecu is fine tuned after every single hp mod)
Btw, in my opinion, this is done not only for the protection of the owner but also for the tuner shop.

CF airbox? Carbon fibre door sills are good 30 extra hp/tq.
Go for the bigest bang for the buck. Paying major $ for a few HP will only get you bragging rights. You could still get your **** handed to you by a modded Mustang.

When we have a client who has a number of mods to his car BEFORE he comes to us for ECU work, I insist on a dyno w/air/fuel ratios. Knowing that baseline allows my software guys to do the custom work necessary to dial in a car for the mods that the car has.
