I know this is probably a stupid question, but can anyone please tell me where the boost pressure sensing connection would be at on my car? And any other tips are greatly appreciated, I don't wanna screw anything up

Think about it really carefully...you can answer your own question.

What part of the "system" sees boost and could be used as a good "boost reference"

Also, think of which sensor reads boost...and maybe get the signal for the wastegate/mbc from the same or similar area.

You are such a jerk, a normal person could never guess.


You can use almost any vac line, but you should really use a large feed, such as a vac manifold running off the brake booster line. Tial recommends boost-only (pre-TB), but thats to put less long-term stress on the diaphragm. Either will work, but the post-TB setup will close the WG between shifts to help prevent falling out of boost.

alright thanks hiprofile I'll give that a shot, and I have another question, To get my ls tuned, do I have to get a jumper harness and change ecus? Or can it just be tuned the way it is?
