where abouts in ontario are you, lol noticed your plate, swear i may have seen that car before... anywhoo ok first thing first, take the blow offf valve on the intake and disble it, remove the brass screw out of the top, remove the spring inside, and replace it with a bolt of approximately the same length, then re-install the brass screw in to the top of the blow off valve.
Now to turn up the boost on the t3, i cant say ive personally done, i had a K24 which is different, so i will draw upon my knowkedge of the cummins 5.9 and hopefully it works, but please reasearch first lol, on the cummins which is an HX 35, what i did was install a small valve in the line supplying the wastegate with its pressure (the line on the compresor side of the turbo that runs to the wastegate) this valve limits the amount of pressure able to enter the wastegatem which changes its opening pressure.
i hope this helps some. lol

What smoken u said im pretty sure is all you gotta do.
If you want to totally disable any boost control and just boost according to fueling, which you control with the pump, you can block that rubber hose on the T3 anywhere you like. if you can find a bolt that fits the hole you can use that with some teflon tape. I personally filled the little brass fitting that's in there with JB weld.
some people think im a dumb ass for doing it but i don't intend on running the car with lots of fuel on the track. its just nice to know im getting max boost for how much fuel im throwing at it and therefore burning it as cleanly as my components can do so. pushing the mileage up a bit.

Smokey Eddy is right, disabling wastegate is dumb ass. You need boost control and fuelling is not way to do it. Sure you can do it, but you wont get decent power that way.

Ok so i can either block the waste gate, or block the tube coming off the t3. But where do i hook up the boost controller.

cut into teh line between the two and put a "T" fitting in. Put the contol valve at the end so you can have a controlled "leak" in the system to fool the wastegate into thinking it has less boost than it really does. more leak, more boost. No leak, same boost you've got now. Simple.

unless your controller is a 'ball and spring' type, then you just splice it in that line, withe the ball toward the intake.
if you have a T3 with two hoses, some extra fiddling is called for, as you have to compensate for the engineered 'leak' which is supposed to be cooling the wastegate.

you can actually have too much boost for a certain amount of fuel. my rabbit used to push 35 psi on a stock un modded n/a fuel pump, doesnt mean it was right, or got good fuel mileage. my car gets better mileage at 25 psi with tons of fuel than it did with 35 psi and almost no fuel. i would run a boost controller (if i could that is) your car will be faster to a certain point with boost, then it will actually be slower. it takes more force to compress 25 psi of air then it does to compress 8 psi of air. the piston is undoubtedly going to slow down more with the more boost and same amount of fuel. maximum boost is not always the best bet.

You'll have to do something about that BOV.
