huperopik, I tiltled the thread "Searching" I think and used '05 SRT6 as user name.
The above is correct and I posted in the Q/A section, this is what I asked:
I am searching for someone that has had a supercharged SRT6 Crossfire or a SLK32 Mercedes ECU upgrade by Inmotion to get their opnion. I have talked with a Crossfire, ( non-supercharged SRT6) just a regular coupe owner that has had a ECU upgrade and they have a problem with spark knock. I've been playing with cars since I was a kid, (30 years) and I know spark knock will heat up your pistons and possiably damage them. With the heating of the pistons on a supercharged motor it would transfer to it and the intercooler would have trouble cooling it. Or is there anyone that has used a Inmotion ECU in any other supercharged cars. I would greatly appreciate any input.
The only reply so far is from Inmotion, and it was:
Hello,
The most common causes of Spark knock are Low fuel quality, Wrong spark plugs or heat range, and a lean condition. Make sure you consider these factors before you chip tune your vehicle. Not only do we work with our buyers to solve these issues, it is possible to adjust the tuning for these factors.

I don't mesn to knock RENNtech but, the SRT6 supercharger I hear pushes 15 PSI stock, does anyone know what they push with the RENNtech pulley upgrade, I would think anything over 18 to 20 PSI would not be safe for the engine. I just don't think in my opnion that 3 or 4 more PSI could make up the difference of 25 to 30 HP that RENNtech is claiming with the pulley & ECU kit over just an ECU upgrade
