Does anyone burn 87 octane or do I have to burn premium gas

So, you added over 150hp....could you please share what you did? Have you taken her to the drag strip for "testing"?

I only do it with all my vehicles. I don't take my vehicles to the strip anymore (67 yrs old).
I added a Livernois ecu tune for up to145 hp gain, a cold air intake from the two turbochargers from Afe power. It adds 17 hp, but I would NOT suggest anyone with a hybrid do it. It was one of the biggest pain in the butt job I've ever done. There is virtually no room for this install. I still get very good gas mileage, if I don't have a lead-foot. I don't get good mileage when I pull a 4000 lb trailer though. I did add a trailer brake controller to my vehicle.
