WPG: Troubleshooting limp mode, looking for vacuum pump.

Hey folks.
TLDR: I'm looking to borrow a vacuum pump to test actuator function.
I've replaced vacuum lines and sealed up a loose vacuum pump nozzle. I'm still getting limp mode in 4th or 5th at anything higher than 2700rpm. Quite frustrating. I have the rear of the engine torn apart to do an EGR delete (leaking EGR flex pipe) and have a good view of the top of the turbo. Before I throw an N75 at it, I'd like to test the actuator function.
Thanks!

You can switch the n18 and n75 around and see if that makes a difference. They do the same thing, same connector, and since you are removing the egr you don't exactly need it any more.

Easy and free!

It ended up being a completely corroded actuator. I bought a Mity Vac to set it properly, so if anyone in Winnipeg needs to use one, hit me up.
