do you know why it will not let me boost more that the stock wastegate pressure of an 18g greddy turbo? i have tried several different settings and it does not boost more than 5-6 lbs. any help will be appreciated...

tested the solenoid with an air line to see if the actuator moved and it did. I also ran the red wire to the battery as well as the black wire from the solenoid and it does tick...

install is set up correctly and it reads vacumm but only to about -9.9 for some reason when compared to boost gauge that reads -20 or so...all other settings on unit work...

com port to actuator and no port to vacuum source...

set % has been set up to 35% and it still will not boost anything but 5-6 lbs.... help...thanks.

 

hmm. could also be a leak. Take a few pics of your setup as not all good "vacuum" sources are the same.

We'll help out. just need to see what you're working with. Trying to diagnose blind, just doesn't work.

 

i do not have camera that i can upload a picture right now but if you think it may be a vacuum leak somewhere then i can check the vacuum hoses but i doubt that there is a leak... however,there a lot of tees from the stock fuel regulator hose that connect the boost gauge, map ,bov, greddy solenoid, and there is a tee that has a hose directly to the boost controller. all the vacuum lines are zip tied tight so can that still be a possible cause why it is not allowing to raise the boost?

also, in order to minimize the tees from the fuel regulator can i run the bov hose directly to the nipple that is on the intake manifold ?

here is a picture for reference... the nipple the not to the brake booster but beside it with a yellow color to it...?

 

Put the gain on 10 or 15, them start with 20% on the set and go up.

Check the warning , may be is setting too low.

 

I dont know if this helps......
My wastegate has 2 air fittings

I have my compressor fitting and 1 of my wastegate fittings on a T direct to one side of the selenoid. The other fitting directly on top of the wastegate going to the other side of the solenoid.

The controller and the vacuum/boost gauge in a T taken directly from the IM.
Hope this helps.
