I ugraded the ko3 to the ko3 2 hybrid which is stock hotside but only oiled cooled and a t3 compressor side. I have a 2000 audi a4 1.8t automatic also have a frontmount and a xo2 bov. The car ran great at first at 12psi after the install then i hooked up the n75 valve and it ran even better at 16psi. Untill the intercooler pipe blew off. Put it back on and ran great again untill the wastegate line came off. I didnt kno at first untill i got home and checked why it was only running 5psi. so i hooked it back up and it still only ran 5psi. so i put it back to wastegate stright to turbo nipple and still only got 5psi unlike when first installed it was at 12psi. The intake was modified to fit i had to cancel the return line off the bov and cancell the crank case regulator thing during install but it did run fine at first with them not hooked up anyone know or have ideas to what is wrong ALL HELP IS APPRECIATED!
