Need some opinons... Safe to run Race gas..
like warr told ya, crank it up to 25 psi if your running straight 100 and above. as far leaded or unleaded you will never know the difference with your mods. (running leaded gas a few times is not going to hurt anything). on a flash your running probably 10.6-10.8 afr's at wot so no need to worry about runnning lean. crank it up and go have some fun.

If anyones still interested in mixing their pump gas, check this 76 92/100 mixing chart. http://www.osbornauto.com/racing/blend.htm

Run VP C16, pull the wastegate vacuum line, pray
Just kidding.
I wouldn't recomend doing things on your own without a logger and hopefully a wideband too (I recomend spending the money up front for something with a NTK sensor. The bosch sensor is cheap to replace, but they don't have a long lifespan. Make sure you mount it straight up and far back from the turbo if you do get a bosch sensor).
There aren't any *good* loggers out there, but a regular OBDII logger for a palm will run you around $150. You can't log knock activity, but you can watch timing to see if it is being retarded as RPMs rise and for dragracing that's fine. It's hard to know for sure if it's knocking in the low end just watching timing if you're not familar with tuning though.
