So I suspected there was a major change to the tune as it took forever for the tuner to update my ECU... so I double checked my strategy and SWPN on the ECU... found this to be humorous...
OLD Strategy: KHDR6KJ
New Strategy: KHDRLME
OLD SWPN: GG1A-14C204-APE
New SWPN: GG1A-14C204-LME
Looks like Livernois had to develope a whole new strategy and SWPN to properly tune the HPFP... cute that they tagged it "LME"....
In anyevent, there is most certainly a change in how the motor sounds.. specifically from 2.5K to 4K RPMs its much more throaty... even compared to the standard V11 tune... makes me wonder how much they changed...
