OK i bought a 86 s4 NA in august of 03, i took it to the track and couldn't do any better than a 16.3, so this winter I wanted to work on my car make it better, It alread had RB cat back and dual bonez high flow cats, I replaced the cats with 3 inch straigt pipe,and added an intake. Next i hooked up my 5th and 6th port actuators to my air pump, and use AMSOIL POWER FOAM, i did all this at once pretty much but i know for a fact the power foam made a huge diff. anyway after doing all this my car idles, runs, sounds and pulls better than i ever thought it could and I ran a 15.2 on bald tires!!! just some ideas that i know work

Power Foam is a product made by Amsoil, it,s made to clean the internal parts of an engine, its a white foam you spray the whole can into the intake while the engine is running, works on the same principal as the ATF and water trick only it works much better and can't harm your engine, and the air pump actuator i just took off the tube from the air pump, drilled a hole in it and stuck a vacuum hos in the hole and sealed it up with caulk, put the air pump tube back on and hook up the vacuum hose to the actuators, now they open around 3000 rmp maybe a little early for some but better than being closed
