Need some advice.

Been running since new, RB Header exhaust system,
(air pump, all emissions removed). Have Bonez air
intake, 30,000 mi. Car runs great. Is it possible, I'm
losing power HP, above 3,500RM. I really don't know
if actuators are opening those extra ports.

 

If you do a search you will find a lot of good stuff....someone recently posted a suggestion to put some grease on the actuator rods, then go out and run it hard, and see if the grease is clean where the rod should have moved.....or have a friend look.

Or, do what I am doing now...take apart the entire intake system, clean it to all hell, get some pineapple sleeves, then you will be pretty dang sure your ports are working.

Right on.

Welcome to the forum, this place is GOOD.
