The custom tune should be able to pull enough timing when on 91 octane? Or do I have to change my driving habits when on 91. No WOT or redline shifts? I think I understand that there is no point in running 91 with the HBP because so much timing has to be pulled but I'm just wondering would it be safe when I'm not near a e85 station? |
This is all dependent on how your tuning is setup with your tuner. A lot of guys are doing 91/E85 flexfuel. So yes, in that case you can run the high boost pulley on 91... If your tuner has setup the tuning for it.
I would not blanket trust all tuners to put in the necessary safety that allows a 93+ octane tune to be ran on 91. I also don't trust myself to not go WOT.
In the end, the way your custom tuning setup is between you and your tuner. The safety of the high boost pulley on your car is in your tuner's hands.
