Hi people I have a Subaru my95 running a fair few mods but turbo is a gt3076
And running simtek ecu I think I might have a faulty boost solinoid so was thinking in upgrading to a turbosmart boost solinoid however would I have to get the car remapped if I fitted one or would it be fine to just do a straight swap

 

yes you'll need a remap to account for the new solenoid - it will be very likely to over and undershoot boost until it's mapped in.
