Able to hold more boost with toluene????
toulene 114
xylene 117
to figure the octane in a mixed tank, just multiply the # of gallons at 93, multiply the # of gallons at 114 or 117, add the two together and divide by total galloons. does that make sense?
example:
3 gallons of 93 = 279
2 gallons of 114 = 228
228+279 = 507
507/5 = 101.4 octane
i usually dont mix any greater than 3 to 1. porsche, turbo vette, and audi guys have been doing this for years, especially where you can only get 91.
i use toulene all the time. i even got a wholesale account at SW for it. i use atf for lube.

This is going to make me unpopular:
Tolulene and Xylene are extremely toxic chemicals. And I mean EXTREMELY TOXIC. We had to have special OSHA classes specific to these chemicals at my old work, so if you are going to handle them, DO NOT LET THEM TOUCH YOUR SKIN. Tolulene enters the blood stream through the skin VERY quickly and can cause nervous system disorders pretty easily, as well as reproductive system disorders and a type of blood poisoning. My trade actually WILL NOT work with tolulene any more because it is just too dangerous and generally bad for you. Inhaling the fumes have nearly the same affect as skin contact as well....just thought I would let you guys know what you are playing with here.

good stuff, but be careful

On the way to work, I found an open stretch of road and nailed it. I was spiking at 22.5lbs and it held 21 to redline. I always test boost spikes the same way... low rpms 3k and floor it.
Here are a couple more thoughts:
The 21 psi was set at 90+ on a hot day - The second run was 75-80 degrees first thing in the morning 6a...
The octane may be keeping the ECU from pulling timing which would allow the car to hold more boost. Not sure if this is the answer though because I ran up to 23 psi on pump/93 octane without any knock or timing pulled on my custom tune which was data logged by AL.

(They don't exist)
you can use lucas fuel injector cleaner as lubricant too, worked great for me, and I trust lucas. Turn a bottle of it upside down and tell me it isn't mostly oils... thickest injector cleaner I've ever seen...
