Interesting you say that you love the thread when you don't seem to have read it.. The engine isn't running any boost, it's NA and he's in the process of giving it a "proper tune" using a wideband o2 sensor. This is the same tool that dyno shops use.
He is asking if anyone has a copy of a M50 spark map, so he can use this information to make some educated adjustments to his own tune which, like he says, is already running quite well using a Megasquirt - a DIY-Kitset Engine Management System - with no "professional" tuning whatsoever.
The prevailing attitude here seems to be that tuning a car is a task beyond comprehension, and can only be achieved by paying mystical engine-wizards who are the only ones capable of understanding how an engine works. This is both funny and sad at the same time.
All these ignorant people who feel the need to tell rds that he's "going to blow his engine up" or that he should "just pay for a tune" can just go home now, obviously the topic of conversation here is way over their heads.
