Hello guys, it seems a lot of us have similar setups.

Mine is as follows:
CP 9:1 pistons
eagle rods
N1 Cams
supertech springs
EFR 7163 T4 Twin with 4 port ebcs and twin port actuator
3.5" exhaust

Been to the dyno recently and I'm kind of underwhelmed with the results.

Horsepower aint that bad for 18 psi. However the shape of the curve is what I dislike the most.

A friend of mine with a very similar setup has a graph that looks exactly the same as mine.

Mid range is great, however, I felt it lacked the top end it used to have when it was N/A.

Is the 7163 choking up top or what?

Same engine just different pistons and turbo setup.
Dotted line is N/A.
