Welcome to the world of SRT6. Mine is tucked away in a garage until summer also.
Sorry about the abrupt initiation, I would also have been panic mode if I wasn't aware of the rev limiter when car is stationary (in park OR in nuetral). Sometimes some people think some things should be know by someone all of the time, but I'll bet they had to learn also

This forum has answered a lot of questions for me, some of them I would not of even KNOWN to search for, like the hood opening to 90 degrees when you release the rod extension with a button on the back of the hood prop cylinder.
Go into the earlier pages in the forums and just look around.
