I dont believe there is a "set" number for boost when adding methanal. I could be wrong about that, but I've never heard of it if there is. What kind of power are you running? Stock internals? Meth, as you may well already know, allows you to run more timing and boost, but there is no spreadsheet as to what boost you run per volume of meth. It just depends on how the engine responds to your mods and its environment. There is no question you can run more timing and boost, but your tuner will be the judge as to where the line ends.
