I just bought a Evo MR 06 and it only has 35000 miles on it but my problem is the HKS-Boost controller it came with doesn't work and the RPM gauge also doesn't want to work either. The boost controller has power but it doesnt do anything while im driving and the RPM gauge is getting a signal because when I do drive fast it starts to move up but of course its not accurate at all. any suggestions?

 

maybe someone had the cluster out and didnt put the needle back where it was supposed to be
