P0300 Random misfire code on Dyno ?

[SilveRT8]

My car is a '08 Vert all stock with 4,500 miles.
2 weeks ago I put it on the Dyno to get basic hp# before mods.
First run was fine with the engine hitting the rev limiter around 6400 rpm, but on the second and third run it cut at 6,200 rpm throwing a cell light for P0300 Random misfire code.
Yesterday I went back to the Dyno and this time first 2 runs were fine but on the third pull it threw the P0300 cell again.
All is fine when accelerating ******* the street and even at the 1/4 mile track for a few runs.
Any idea?
Next week I want to go to the Dealer to get the Mopar Controller installed, should this be addressed before doing the Controller?

Make sure you have the latest calibration for the stock module... a calibration update was issued for 08's with P0300 issues.

Thanks for the reply, mine was made 02/25/2008, so maybe it does not have this update.
