Will a supercharged car benefit from alcohol inj with no timing advance?

I would run a M14 but you would have to scan as there are many variables in this. A scan tool is the key.

how much boost are you seeing?
Do you have any way to moniter to see if you are getting detonation?

I am running between 10-17 psi of boost. Quick question, where would be a good place to tap for my boost gauge? I have been getting some funny readings lately and need somewhere different I think. The gauge is always showing the engine making boost. Even idling. I beleive it should be in vaccum until the throttle is pressed? If I unplug the boost gauge and put my finger over the port it is creating a "sucking" effect idling. Any ideas?

anywhere in the base of the super charger. where it bolts to the engine. anywhere that there is positive air pressure

So, since it is acting up. Would you suggest it is a faulty gauge?

Found the issue. My boost gauge was giving a faulty reading. Autometer must have let that one slip by.
