Okay, I am just installing Julio's Alky kit, hopefully wrap up this weekend with the install and then start tuning.
I am wondering about the base octane of gas to use. Where I am at almost all stations have only 91 octane max. I bought 5 gallons unleaded 110 octane which I have been running, adding 1 gallon to 12-15 gallons 91 oct. According to charts, raising the overall octane to 93. I carry a gallon container in the trunk when I know I will be filling up.

My question comes in with tuning on the Alky. Should I not mix the gases anymore and just run 91 oct and tune the Alky system with that? or should I continue to boost the octane to 93 like I have been doing?

If I tune with base octane of 91, would I just be using more meth to compensate?
Or should I just keep doing what I am doing so I have a base octane of 93?

Thoughts? I'm just thinking of eliminating a step if its okay to do it.
 
Use your 91 and start at low boost work your way up. Why add anymore to what you have?
 
You'll be fine, been running 91 and Methanol for years now. If your TT chip wasn't ordered for 91/alky you *may* need to adjust timing slightly.
