Yes, that would be me... and for my truck, yes, the fact that I'm putting an MS3 on a stock 4.8
is overkill. It does make sense for me in a wider context, though: I work for one of the biggest MegaSquirt distributors, so this is kind of an exercise to better support customers who are running MegaSquirt on these motors. (Unfortunately, I wasn't able to convince the boss that paying for a blower kit would let us support LS customers even better.
