This is my S4 N/A with a "mild" streetport. I felt he should have spent more time on the smoothness of the ports but oh well...the rebuild was free for me. Engine has about 4k miles on it.
Has s5 LIM due to s5 midplate. The 5th and 6th port actuators are only opening up about half way since its electrically activated with some vacuum pump thing....its retarded and I need to fix it. How much more power would it bring with them fully open? I wasnt allowed to take the actuators off while it was on the dyno to see what it would do with them open
I plan on getting the rtek 2.1 for this in the future to see if I can get close to 200. that would make me happy.
P.S the AF/R was like an o2 sensor they stuck up the exhaust pipe O_O

I do have a full RB exhaust with a presilencer. I have been trying to find an S5 UIM but not sure how I would hook up the solenoid since the ACV and most other vacuum related items have been removed.
