Shiv, how much more timing are you able to advance with the meth tune v. your regular non-meth tune? Also is the a/f changed for the meth tune? I am assuming you can run much leaner with meth as well?
I ask because looking at the dynos, it looks like you could be getting more from the meth with a tune. Considering your tune alone gives 15hp, meth alone with no tune gives you 10-15, you would (or I would) think a meth specific tune being able to almost be a similar tune you could do for 100 octane could yield a higher result than simply adding up the benefit of both above.
Is the methanol tune similar to a tune you would do on race gas?
