How many times am I going to say it, WOW nicest P1 ever

Forgive the possibly stupid question, with the meth mix in the fuel it means that you are running the map for 20% at all times!, or would filling up with v power and switching to the appropriate map not cause any issues, obviously some meth mix would remain. would going for a meth injection kit not give you more control over when you run v/power and or meth? (hope that makes sense) with a seperate meth bottle/tank for the injection system, would also enable you to stretch the meth with a distilled water mix, something which you obviously cannot do with the main tank system.

Also with meth injection comes increased cooling, again giving increase in power, however nominal, does the characteristic of the 20% meth mix by mixing in the main tank provide the added benefit of a cooler combustion also?

30bhp sounds reasonable for 20%, out of interest what figures were you expecting?
