I've got a hybrid so probably best to stick with grainger. See you on the 25th.

Glhnslht2, hmmm, I have the 87 T2 LM in my car. What's the story on the two different settings. Where are they located? I have found one location. As far as the spring thing I will probably go back...

Jeff, Yes, I will be at Jackson's with the car. I found overboost and sure enough it was set at 13.29 psi. My scans showed me 13.3, so that was the problem. I would like to talk with you at Jackson's...

That last sentence caught my attention, particularly the SHORT DEDICATED. I will definitely change that, at present I had it back on the hose to the valve cover. The most obvious is one of the ports...

I looked for that before but somehow missed it. Does increasing the number raise the the overboost point?
Thanks

With an LM, can I turn off the over boost function? I do have my grainger installed correctly and it has a vent.

I have since put back everything along with putting the weakest spring into the Grainger valve. It doesn't over boost but runs at about 11psi and holds so the can is good. I just don't understand...

I have a grainger valve.

It started to do this again so I Ran an MPscan, boost going all the way to 14.7 and likely beyond. I suspect that somehow the wastegate can is hanging the waste gate shut....

I put everything back the way it was and it worked properly again. I also tried taking vacuum off the throttle body, that worked as well.
I hope someone can explain this to me. It doesn't make sense.

I decided to change how I had my boost control hooked to vacuum. I was getting vacuum from a "T" on the intake manifold. (This "T" also is connected to the brake booster.)
Into this hose an I...
