Go ahead and use se zip ties. And tie the oil drain line in place so it will not bump you ac compressor pulley or belt.
Not sure about jumping to 15 psi all at once.
I like your idea. Stating small and working up. That's what the boost controller is for.

Here is a closer pic although the zip tie is not showing in the pic.
We will see how things will go with the tune. The tuner is confident that he can handle it in one session tuning for 15psi. He wants to save his time and my cost for tuning. According to him tuning in two steps, for 9psi then for 15psi, will be similar to tuning twice time cost wise.

Just buy this 2 bar sensor which is a direct swap. If you aren't going over 15psi you don't need to lose the resolution by going to the 3.3bar sensor.

If you decide to get rid of your maf then you can buy a sensor like this.

If you go with an iat sensor like that you have to cut two wires out of the maf harness and run to the iat sensor. You don't need a bung for it. I drilled and tapped my intercooler pipe and put it in with rtv and it hasn't leaked in 5 years. You can leave your maf in but I have blown two of them in half so I deleted it out.

Thanks for the advice. It's already zip tied to the cold pipe going from the turbo to IC. So, that oil drain line will not move an inch from it's place.

I don't know if I would jump all the way to 15psi. Start with 9-10psi until you get used to it and then start turning it up. If you use a 2 bar setup it doesn't take long to dial the tune in at higher boost. I just tuned my turbo s10 at 9psi in about half an hour on the street. When I turn the boost up it should only take a couple of pulls to dial it in at the new boost level. The nice thing about 2 bar SD tuning is you can run any boost level. I pull a lot with my big truck so I have it tuned from 1psi to 18psi. I run low boost (10psi) all of the time until I want more and then flip a switch and go to 15-18 psi.
I checked with another person who know about tuning and he told me that what the tuner is talking about is MAF tune (not SD) with stock map. He will rescale the MAF to make the max maf reading work to the limit fueling 15psi or something like that. Not sure I used the correct words to describe it.
So, he was talking about maf tune not SD tune.
Also, I don't think my stock 4L65E with trans go shift kit will be happy with 15psi.
Anyone take a guess what rwhp I should expect at 9psi and also at 15psi?

I would guess 500-525rwhp on 9psi with your cam. On 15psi it should be 675+ depending on which 76mm turbo you have. What exhaust wheel does your turbo have? I would recommend getting a meth kit before you push 15psi on pump gas.

Is it because of gate restriction? should I worry about over boosting more than the WG spring rating with Precision 46mm gate.
I should keep an eye on boost gauge then when tuning it with 9Ib spring.
