agallardo...
BCS is Boost Control Solenoid...I noticed a slight jump once I took mine out...takes all of 5 minutes to do. But like Talon says, just a piece of black tubular plactic that comes out and allows more boost through...

 

well maybe not $200,i just bought a mbc and an autometer cobalt c2 mechanical gauge for $115.factor in the $30 3 gauge pod holder and its closer to $200 hehe.WHAT IS THE DIFFERENCE BETWEEN MECHANICAL AND ELECTRIC GAUGES BESIDES PRICE?

 

The electrical guages are way more accurate and less prone to break or not work properly

 

Dam...should i regret getting the mechanical gauges,i already have 3,not installed though,i plan on doing 7 altogether,would it be in my best interest to get the rest electrical,or just stay mechanical since i already started that way??

 

dont get me wrong, mechanical arnt bad. They will get the job done for you. Why do you need so many guages??

 

well its not that i need them all,but i think the idea of being able to tell what going on in almost every aspect of the running order is cool,plus i went with the cobalt c2 gauges and they emit a bright blue light at night,look very neat.im doing air fuel,oil press and boost on the pillar,oil temp and fuel press on the cluster and not sure if i just wanna do that 2 1/16" digital tach/shiftlight by itself in the center vent or do water temp along with it.....back to my previous question with the remaining gauges i have yet to buy,is it a smart idea to go with electrical or just stay with mechanical since that is what i started?thanks engineer for everything

 

well some of those i think are electrical anyway, like the oil temp and the water temp if im not mistaken. But if i were to get guages and you really want to know everything you really need to know. These are what are important IMO

- Boost Guage (obviously)
- WideBand O2 (dont get the narrowband, unless you already did)
- EGT Guage
- Oil pressure
- I guess fuel pressure would be good but you only really need it if your gonna upgrade fuel then you might as well get the FPR
