Dyno today
Faxing RENNtech the Dyno graph tomorrow.
1st Run 477.93hp 526.44 trq
1 minute later
Can you say heat soak????
459.28 hp 511.41 trq
Was kind of expecting a bit closer to 500-510 rwhp.
Gasoline:
Dyno guy said Chevron is the worst - use union 76, I have always gone out of my way to use Chevron gas.
I was a bit disappointed. I'm thinking/hoping RENNtech, after looking at the graph, will want my ECU back to reflash.
Next move is looking into the best way to cool down the supercharger.

thanks
They are mounted on the valve stems just as the stock rims were. They are not strapped/banded.
It is an issue with MOST aftermarket rims now (07's tpms) but not with the RENNtechs.

If you can post the dyno and A/F graphs. Are you considering their new I/C upgrade ?
Also let me know how Renntech responds. If there is more power to be had from ECU programming or additional dyno tuning it would probably apply to my car too, since our mods were done at about the same time.

I got very similar numbers (478/540 on Dyno Dynamics) for the CLS55. My Stage 5 is basically the equivalent as your Stage 4 since the 2007 SL55 already has the larger throttle body.

I am researching cooling the supercharger now.
Updates will follow.
