Going tuning, race gas or pump gas?

[Drewcool2]

I'm going tuning this weekend, and I'm trying to decide whether to tune with c16 or just sunoco 94. I've got dsmlink so ide really like to add some timing with race gas to get some nice power out of it, but I still only drive every day on 94. I don't know, maybe I can do both. Do the guys at Turbotrix get people that empty their fuel tanks on the dyno and add race gas after they've tuned for pump?

The best thing you can do is tune for both. Start with the 94, get that tuned as best you can and then put c16 in. I would just drive around till your fuel light comes on then pour in the c16. This way you'll be tuned for daily driving 94 and when you go to the track you can just load the c16 tuning file to the ecu and your good to go. When you put 94 back in then just load the 94 octane file. I love dsmlink, makes things so easy.
