Wednesday night I should have some dyno numbers from my build

Where is a good spot to put a t in for reading boost Anywhere in the vacum line or what?

He told me if i set up the t before hand it will be quicker so less charge for me ANd he also has a hptuners guy that knows boosted cars Im really considering just getting him to tune it and geting a hptuner later


Im just happy to finally get some numbers It is a mustang dyno (to get true number) his words not mine
But hey gotta be proud of what you work with
