boost problem

[liv4gnz]

first off there aRE NO BOOST LEAKS THIS HAS BEEN CHECKED

the lines are all new


i set the waste gate at 17 pounds it shoots past 20 than drops down


when i was at teh track launching off the foot brake i let go the boost kicks up than drops to like 14-15 than goes back up but on the street it pulls like twice as hard idk wtf is wrong


i think it has something to do with that restricter y fitting from the wastegate and cold side of the turbo into that sensor can any one enlighten me on how to route those 3 hoses?

You might need to port the WG hole.

The boost line gets routed like this, the small end (5/32) goes to the wastegate solenoid (on valve cover) the "y" restricted end goes to the turbo compressor, and the other end to the wastegate.
