Yea, the stock tune was for the naturally aspirated 4.6L, actually now that I'm thinking about it, it was a hi-performance tune for the 4.6L that was tuned by Troyer. I guess to be honest, I am not even sure what tune ended up in the darn thing. I guess I should check it with the tuner when I get home.

As far as the pumps go, I do realize that the two pumps were separately controlled units on the stock L, but without spending an extra 300 bucks, I opted to just have both 155L pumps working together off of the same leads that I spliced together. While on the dyno, there were no fuel issues, the psi never dropped indicating that I didn't have enough fuel. So for now, I have to go with the two stockers.
