I just have a couple questions. I am gonna be running my gst on the track soon and currently as a DD on the streets. I am running our crappy 91 octane+meth/water injection on the streets with my 20g.

i was wondering if i were to go to the track if it would be okay to run the 100 octane unleaded(which is sold down the road from my house)+ injection at the track. (of course i would properly tune with a switchable/different map)...

also what a/f ratio would i think about running with the race gas/ injection? already know what i will be running with my crap gas/ injection. lol
