Default Tst powermax cr install help PLEASE.

So I've got all the injectors and sensors hooked up. I'm now to the part it wants me to connect the wore fuse tap to fuse 36 and 50, BUT not if you have a "pusher pump". Well I have an airdog 150 do I have a pusher pump right? So I should not hook it up this way? I also don't have a "fuel pump relay" in my fuse box so I'm not sure how to even hook power up to the lift pump/pusher pump. Can anyone help me out?

Nm. I misinterpreted the last part of the instructions. But I've got it all hooked up and I have an issue...my boost peaks at 22psi now. Gets there fast and the truck feels faster, but I was able to hit 32 before. I'm reading off of an edge cts monitor. What's going on?

Can anyone guess why I went from 32 with the smarty jr to 23 with the powermax hooked up?

Talked to tst and they say it's because the cts monitor that I have is reading from the OBDII port so it's getting the computers max boost reading of 23psi. The tst is boost fooling the computer so the truck doesn't defuel if it does over boost. I'm probably getting more boost, but the computer thinks I'm getting. I more than 23. That was my understanding anyways. I guess I'll have to set up a different boost guage.
