hey guys i thought id share this with you since couple people on here reported driveline noise between 20-40mph under part throttle

so i bought my truck 2006 inferno red srt8 3-4 weeks ago from the original owner but it never seen the dealer no big deal to me i dont go to the dealer either but i figured ill go for the flash update since you need it for the diablo tuner, so i went on wkjeeps tsb section and found the newest update which was TSB 21-013-07 which i thought would superced the
TSB 21-020-06 but it didnt since the 21-013-07 was for FDCM and the 21-020-06 was for the TCM i guess its a separate system, but what it did was cured my driveline/Tcase noise completly and i thought i was in the market for a trans or Tcase i was so happy with the result that i went back and got the 21-020-06 done too

now the driveline is quiet and the TCM is up to date too ready for mods lol

FDCM, but yes the update cures the driveline noise. Not sure how or why, but glad it does! :D

i would just incase if they flash the ecu your tuner might get locked out and than goodluck getting it unlocked i guess its a big process with diablo, on the other hand they shouldn't mess with the ecu but you never know with the dealer and for sure if you still have warranty they can void it if they find out its tuned
Is this a thing with just the o6s
I have an 07 and have a noise that starts right in around 60kilometer/hour.
It's sound like it may be a wheel/hub hearing but all the wheels are solid no play... there is slight play in driveline. I can turn it bye hand a roll the rig a little if I don't have the park brake applied.. but then it locked up..
Normal???
