alright so heres the deal im hoping i dont have to replace my turbo i dont think i can afford that but my car seems to lack in power quite a bit. and my boost guage only goes up about half way. i think it would be about 25 x10mmHg and i checked my presure comming out of my intercooler as i was told to do and it was low very low. and then i was checking for leaks cause i dont have the time to take everything apart to get to the turbo i noticed that next to my pressure sensor is my variable resistor and it looks blown to crap. but im not shure of what its controlling i dont know what it does exactly i know what a variable resistor does i just dont know what this particular one does for the car. its right next to the pressure sensor any help, advice, experence, anything would be greatly apreciated. thank you.

 

even if this resistor isnt functioning properly you should still be able to make boost( at least i think so). check for leaks( look around the resistor also), possibly a bad bov, or bad turbo( check for shaft play on the intake side). A Haynes manual for your car would most likely explain the operation of this resistor. I dont know much about them either but i would think that would variate the pressure with some sort of baffle to help get rid of off throttle booste(dont qoute me on that). you can get a haynes manual at Advanced Auto parts or AUTOZONE. hope this helps.

 

thanks ill keep you posted still looking for a new resistor found one at a mazda parts place but it was a houndred bucks forget that so im checking out some junk yards.
