I have a MY94 wrx currently and I have recently purchased a Power FC for it. Im just curious what exactly I should have or be prepared for when I go for dyno tuning. My current mods are TBE, Walbro 255 pump, ForresterXT tmic and a boost gauge. I was thinking maybe a MBC might be a good addition so that boost can be set appropriately. My goal is to get the most out of the stock components with my current mods. Any advice, warnings etc would be most appreciated.

Thanks,
Garrett

 

no need for a manual boost controller if you're going to have that FC mapped.

 

Just out of curiosity does the FC have some control over the stock boost cluster? Just wondering how the mapping will affect boost control. I dont have the separate boost control add on for the FC.

 

The power Fc will have complete control of boost and will be set where the mappers see's best, you will have more RPM specific boost control with a separate boost controller like the AVCR

 

Stock boost control will be fine to 1 bar , for boost control beyond this you will require the boost control kit , a later 1.7 bar map sensor or an MBC...

 

what Martyn said except the later 1.7bar map sensor doesn't read correct on the early pfc.. I tend to use the map sensor from the boost control kit.. the standard 3port solenoid is fine.
