I am thinking about running a Meth/water 50/50 injection kit. I am not necessarily wanting to retune to be dependant on the Methanol but I am want to run it to keep my AIT temps down so my sensor will not have to pull timing when it is warmer out. Is this possible, can I just get a 50/50 kit and hook it up or will I have to get retuned? I planned on getting a psi switch and set it to activate my meth at like 4 psi. I am only running a 8 psi pulley. ........STLWAGON where are you at? I need your advice.
