What gas and tune for OFT?
 

Hey guys,
Advices needed.. I am running TRD intake + TRD exahust + OFH + OFT.

What gas and tune do you suggest?

Right now I'm on UEL Stg 2 91 Oct. I use Husky 91 Oct gas. And am happy with the performance..

I am considering changing to the UEL Stg 2 93 Oct. tune and using Petro Ultra 94.

My main objective is to see if i can get any more power, but without becoming offensively loud. I tried Shell a few times and the car became too loud for my taste, wondering if ultra 94 would cause the same..

Thoughts/experiences? Any noticeable difference going from 91 to 93 tune?

I don't think you will notice much difference unless you dyno the car. I think it's roughly a 5-7whp difference.

Hearing a volume difference between gas brands is likely in your head. I run shell or petro 91 on a 91 tune in the winter and petro 94 on a 93 tune in the summer and there's no difference in volume.

As for the power difference, it is noticeable above 5000rpm between a 91 and 93 tune, but isn't going to be massive.
