I'm hoping someone can point me in the right direction. I have no idea what has happened. I installed the tillix kit a couple of years ago, set at 14psi boost and it's been great until a month ago. Started with the boost creeping over 15 psi with the ensuing limp mode activation. And it crept up to 20 psi over a few days with the limp mode activation increasing proportionally. Of course I tried to restore the happy days but no, its like the whole system has been overridden by who knows what! I've cleaned the maf sensor, looked for splits and holes in tubes. Could it be the maf has failed? Any help would be appreciated.... before baldness begins.
