I just bought a 93.5 TT with 6-speed and it has an HKS ECV IV Boost Controller. I have no idea how this thing works and can't reach the prior owner that had it installed.

I would really like to take the new car for a drive an stomp on it, but I don't have any clue where this thing is set or where it should be set.

Can anybody out there give me the basics just to be able to take if for a drive and know what kind of boost level the wastegate is set for.

Thanks!

ruup2it--
Thanks so much!! Everyone on this forum is great & this forum is quite a find!!

I have a boost gauge on the car. Any idea what the peak boost (in psi) I should see is? I'm not sure what the boost would be on a stock car...

When you say underboost and overboost--what boost level would these be?
