[Hi Volt]

Hey,

There was no screen above my filter, my truck is an '01 perhaps they were used on later years ? What does this screen look like exactly ? Is it fine mesh or more open ? Part of the airbox or filter ?

I have thought about some possible fuel alterations, but first I am purchasing an Auto Tap so I can watch the fuel trims, O2's and other sensors to get the whole picture. From the economy point of view, the truck certainly is not running over rich as economy is up. Then I am not sure whether I will buy a controller or build one based on what I feel the engine wants.

Did not see the Forerunner post, but unless we are dealing with the same engine then not all mods will necessarily react the same. For example, the shape of the air intake, or location of the MAF on two different engines can get two different results from a CAI, one may work, the other may lose power. The fuel map strategies can also vary between engine types thus rendering a whole new set of fuel trims for a given change in air flow.

I am planning on trying dual exhaust, and then will measure my airbox again to see if there has been any additonal scavenging to cause vacuum to form again at WOT. I am going to restist the temptation to throw on a number of things at once, I want to do one thing, optimise it and move on ( at least that is the plan ! )
