very cool upgrade!!
have you found any problems with this system?
where did you take the manifold air pressure reading from? was is a splice into the MAP sensor port?
i was thinking of doing the exact same to mine but wondered if you ran in to any problems.
any pointers would be greatly appreciated :)
How much did that cost?
