How is the condition of your actual vacuum T that goes onto the LIM nipple?
By 80k miles and several removals/reinstalls, my T was cracked and I had to shorten it which eventually lead to it being sucked in and out partially blocking off an accurate vacuum reading to the MAP.
Don't be forced to buy the entire vacuum line kit from ZZP or the dealer.
My friend and I are currently working on molding silicone vacuum T's out of fire tape.
I'll let you know more details when we mass produce them and start another thread for sale.
