I am headed to Renntech to get my ecu upgraded. Any thoughts on which tune to do, the intermediate or full?

This car is my daily driver so I still want it to be somewhat docile. I have an SL65 for the weekends when I want to get really crazy.

Thoughts or opinions please???

trust me this one will feel quicker than the 12 cylinder with a stage 2

Thanks, I did the stage 2 and I still need more power so I am glad I didn't go intermediate

Ditch the canned tunes of various stages, flavors, varieties. Get a custom dyno tune or road tune.

I Renntech tuned my E63S, add down pipes 200 cell cats.
Only way to go!

Im not sure if Im reading this right... Renntech downpipes with 200-cell catalytic converters -- $4780 (uninstalled)

Gains -- 10hp and 15lbft

hows a dyno tune or road tune differ from a standard tune?

dr. ss

Road tune/dyno tune are actual tunes tailored to your car, dialed in real world (especially a road tune). Email tunes/canned tunes/odd the shelf tunes are "one size fits all" tunes, sometimes they ride the knock sensor, or I'll have issues like one step colder plugs and all that noise.

If available a road tune/dynotune is preferable for a one for all, all for one tune.

but only possible if u are local to the tuner, correct?

Correct. Unless you have data logging capabilities and send the logs to the tuner so they can make changes based on your logs going back and forth until everything is perfect. I don't believe this is an option though with Mercedes as i've never seen or heard of data logging software available to the consumer.

Yes, those 200 cell down pipes are expensive from Renntech!
Go cat less ?
