In effect, I would be lowering the octane of the fuel by adding the meth in. If you're staying with bolt-ons, you would only need a fuel pump and injectors if you plan on running E85. 91 shouldn't need it.

Thanks for the clarification. Wasn't sure the octane value of meth. I would definitely prefer just E85, not necessarily for any power improvement, but as stated before, the cooling properties. It's just a bonus for me that it's more efficient. This would most likely be done for FI, not NA. I'm expecting a drop in over all psi with the headers, hoping to still make the advertised amount going to SC option.
