I used both stp and Berryman. The problem I had, the pipe that attaches to the throttlebody is hard plastic. The hook for each collapses. The STP should empty in approximately 12 mins. After 18 it was only half done. The Berryman same with hook but they say the engine should be set at ideal, it kept stalling and only 1/4 used after 10 mins.
I e-m STP, they told me to use the hook after the MAF. The stuff would go into the turbo, pipe, intercooler before it goes up to the TB.
