[heyman]

I thought I saw a thread somewhere here about how to make a manual wastegate and now I can't find it could somebody please point me in the right direction?

There is mention of it in the 6.5 Technical Library... a DIY article by mfguru, complete with pictures!

Thank-you very much

Won't you get an an ses light 78 from the solenoid not operating or sensing a vacuum? How does one overcome this?

Nope. The PCM doesn't have a vacuum sensor for the solenoid, it just senses whether the boost is working or not. When it's not, it thinks the solenoid is bad.

If you have an 'S' engine and need to keep the vacuum for your EGR, just plug the line coming off the solenoid.

It does once in a while and goes off but I ignore it.

Its caused by over/under boost compared to PCM program boost curve. normally overboost with a TM. A "boost fooler" look it up in the library will solve the overboost problem.

I found the thread right away after adding to this thread. Thanks for your input guys. There's a really great breakdown for dummys with a potentiometer so you can adjust the settings of the boost sensor. That way the sensor can still give the light at the settings that you want. Great to have guys with this knowledge willing to help people like me. I hope to help others too someday.
