How to find a BAD vacuum leak?

I used duct tape and it worked fine. Just make sure it is pinched or folded over and it will seal.

Now, with the retune leaning it out 60% AND using the stock 22 lb/hr injectors it runs a tad lean around idle if I keep open and closing the thottle to allow it to run, but if I hold the throttle open it lets too much air in and doesn't add enough fuel and it just dies out.. So pretty much if the leak is at a hose, it should be so lean that it shouldn't even run.
