Owners of JK 3.8 with supercharger, your opinion, please
As far as I can see in the manual, the red line of the engine - 5600 rpm, but I feel my engine equipped with Sprintex supercharger can more and more easily... like Pentastar...
if I configure my tuner settings upward of red line, as it will be safe for the engine?
Thanks.

I agree. With the extra stress already from the supercharger, increasing the RPM limit with most likely end up destroying the engine. I would NOT do that. At that point the power from the engine is already past the peak and starting to decrease anyway.
