I am kinda playing with the fuel mixture now with a boost controller, I figured out how to give it more fuel using the boost to help it, and when I let off the pedal the boost goes away, and so does the fuel, no boost, no fuel.
I still have the vacuum issue though, and I just shortened the spring to much and it didn't help, it just don't idle as good, so I stretched the spring a little and now it idles good again, you see if I have a high idle, I have less vacuum when I let off the pedal, if I have a low idle, I have more vacuum when I let off the pedal, when I talk about letting off the pedal I mean that I am cruising down the road in second gear at about 2000rpms and let off the pedal completely I get 5psi of vacuum, if I almost let off the pedal all the way I only have 2psi, it's hard/strange to not let off all the way, but I am learning how to drive it, I don't know what it does in fifth on the hiway right now as I just got it tuned in today, and I have not had it on the hiway today, I will find out tomorrow when I go down town to pay my property taxes and get tags for 2 of the trucks.
Vacuum pulls oil thru the seal of the turbo, the more vacuum the more oil gets pulled thru, I know this because the inside of the intake is coated with oil.
The vacuum valve was coming apart again, the holes were elongated again, so I drilled 4 more holes in the tube and put 4 screws into the PVC, it is just to hot in the engine compartment for PVC, I am going to have to come up with something made out of just metal.
Here is what I did today after work, I put in an oil filter sandwich adapter kit so that I could mount the oil gauge sensor/sender without worrying that it would break off again, this is what I bought on ebay.http://www.ebay.com/itm/Racing-Sport-JD ... Sl&vxp=mtr
Here it is mounted, it doesn't seem to be leaking, even though it didn't not seal properly the first time I tightened it down, so I started over and got it right the second time.
It got kinda oily below the filter when I removed it to put the adapter plate in.
I am hoping this sensor part is done now, it had good oil pressure, it almost pegged the 90psi gauge when cold while idling, but after warmed up it was about 50psi at 750rpms, I can turn it down to about 500rpms if I want, but it makes the truck shake.
