Just want to get some feed back on pound by pound spool up and what you think is safe as your spooling up as far as PSI to AFR?? For example if I'm running 27PSI from 2PSI all the way to 27PSI what is a safe AFR?? Example at 2PSI it safe to run xx.xAFR and so on all the way to 27PSI?? Thank you for your time.

 

What fuel?

 

I'm interested in this as well. I have my car dialed in well at idle, cruise, and WOT but I get nervous with part throttle boost situations. Right now I see about 12, 12.5:1 AFR at 10 psi. I'm using 93 octane. I am tuned to low 11:1 (11.2 or so) at WOT, 25 psi tapering to 22. I haven't logged the car at part throttle really so I'm not sure what load that would even be, I'm guessing 160-200 or so?
