    When you do the leak test, pay close attention to the coupler from your turbo to the under-routed hotpipe. That little guy was tricky when I ran the HTP under-route hotpipe.

    To help understand LTFT

    Pre-turbo = + trims, air added or sucked in
    turbo to TP = - trims, air lost or pushed out
    post TP = + trims, air added or sucked in

    Check the entire intake tract. Start at the MAF housing, and make sure that the silicone couplers are properly attached, not cracked or pinched, and sufficiently tight. Then move back towards the turbo from there. Check each coupler and connection on the way to make sure that nothing is pinched, cracked, or otherwise damaged. Make sure all the clamps are properly tightened. Then check the boost tubes (the intercooler couplers). Make sure that nothing is pinched, cracked, or othewise damaged. Also, make sure all the clamps are properly tightened. Do this on both the hot and cold side of the intercooler.

    Also check vac line coming off on charge pipes. Zip ties dont really keep the pressure at bay. If it's all you have pull 3 zip ties as tight as you can. Then buy a hose clamp that works.
