Any of the senior members have any idea of how much timing is pulled on a srt6 with the 89 octane setting,our computers have three settings from the factory,my buddy used a Star diagnotics tool to go into my ecu and put my car on the 89 tune.Now I already had a inmotion tune since I am modded but that allowed me to run a 175 shot of nitrous for about 3 years,it was for street racing only which i dont do anymore.You can feel the difference on the 87 octance vs the 93 octane setting but not 89 to 93.
