New tires to go with 93 octane - e50 flex tune

[AJRMKV]

CTS turbo, EOS mani, PI/reflex, Meth, flex fuel, XHP, 92 octane, catless DP, 27-28 psi. It did 562 whp on DI, catted DP, and a couple pounds less boost. So I am swagging that the final tune with 2-3 more psi, no cat, a couple deg more timing and more meth gets me close to 600 whp.

Are you using meth as an octane booster?

At this point yes, I use Ethanol and or Methanol in a water meth system to increase octane on pump gas. Sure it cools too for an added benefit. I don't need it for additional fueling as I have PI/DI. I used to run 50/50 water meth but my tuner recommended pure meth, for octane, if I felt comfortable doing so. I tried methanol and then ethanol with good results.

Which kit do you use?

Snow, but AEM or custom built would work too.
