Dunno if a few $k would sway my choice. I'd much rather go with quality, not that we have any signs that Kleeman or Evo are lacking. Point being, is Renntech "better" in any way? mor precise, better QC, better reliability?

Jangy,

May be you and I will hit up EVO stage 2 and ask them for a discount for your car and mine.

I don't think there is much difference between Renntech and Kleemann if you are only getting ECU and pullley. Beyond these mods however, there are certainly differences.. Particuarly with repect to the headers. Do you want to keep your primary cats? Renntech headers (and Evosport) bolt directly on to the factory downpipes. Kleemann headers have their own downpipes which remove the primary cats. (they are beautiful headers, but you lose your cats).

Interesting enough, Helmut of Renntech used to work at AMG. Think he might have actually been one of the founders (but don't quote me). Anyways, it is my understanding that they still have a very close relationship with AMG.

If you have access to the Evosport shop, I don't think there's that much of a question is there

Evosport all the way, especially since you can visit them in person, take a look around and what not.

If you don't want the Evosport power packages, next up would be Kleemann. From my time on MBWorld.org I've always found Kleemann to be on the good side of almost all the members stories.

I'm not saying the other tuners are bad, it's just there is a lot more experience with Kleemann on the boards from what I've read than anything else (I'm talking about full blown packages, not just a pulley and chip).

And another thing Jangy, Evosport just doesn't sell Evosport and Kleemann branded products. They sell an entire line-up of Mercedes products so you can mix+match.

Just thinking outloud, but it's something to think about, sure beats either going across the country or even to five different shops for all your mod needs.

I have had my Renntech mods on my SL55 for a while and have not had any problems. The dealer here in Sacramento did the install without any problems. That in itself is a testimony to the quality of the Renntech parts, since this dealer typically can f**k up a steel ball with a rubber hammer.

Set it up bro, I'm ready $$
