looks good.
so you just went from your wastegate into that pipe and just put a tap in the pipe. and then just caped off one side of your tee for the boost gauge?

well where im tapping into there used to be a grid heater there, i removed it and put a plug in its way, then i got one that was tapped and run the waste gate off of the engine intake psi.

not a bad idea. so the heater plug isn't really necessary? and will this prevent me from doing other things? (idk what the "other things" would be of course.)

well the intake heater aids in cold weather starting, but you already got glow plugs, and i do live in texas, i dont even use my block heater. so i deleted mine and put a plug in in it, then i went ahead and got another one tapped so i can see how my turbo responds when it gets its boost reading from elsewhere since there is a drop in psi after the ic.

so far i like it

oh okay. well the coldest it's been when so far when i've started my truck was like 20*.
i may not change up everything right now. i'm definately gonna buy a longer hose so i can put my boost valve back in. but i'm gonna wait on the other. keep me posted on how yours runs. like if anything out of the ordinary happens.

here's my boost increase valve and tee. i fixed them to how they are supposed to go. i could probably get rid of some more hose. but it doesn't bother me right now. i am still only running 25psi which is only 2psi over stock.
