Stage 2 Mapping Octane Question + BCS
Hi all, I'm currently running a 93 octane Cobb S1 setup.
Planning on doing a S2 install next month (high flow intake + Turboback).
The wagon will get (pro) tuned after the mods are installed.
Here in N. Illinois, I can get 87, 89 and 93 octanes just about anywhere.
The car needs to travel out of state (read: 93 might not be available).
Question is, what gas should I bring to the tune to make the car drivable everywhere?
The way it's been explained, basically, to me is that you don't want to run any octane lower than the current map is tuned to, and that identical octanes are not all the same due to their respective mixes. Which makes me ask, what's the minimum I should tune to and what are the pros/cons to this approach??
Don't necessarily want to tune for 87, run 93 (when I can) and take a performance hit(if at all?). Am I looking at this issue the right way? What/how are all you S2 folks running?
Also, if anyone has a good link to a BCS discussion (a 3 port BSC is being recommended by my tuner), would also be appreciated.
