roger.svoboda Posted July 29, 2006 Share Posted July 29, 2006 Sounds like you blew off one of the vacuum hoses someplace. Buddy of mine did that on the dyno with a 300zx Quote Link to comment Share on other sites More sharing options...
mario_82_ZXT Posted July 29, 2006 Share Posted July 29, 2006 Check the TPS as well. Also the stock POV will go off at like 8psi, it needs to be shimmed/removed/replaced to run more boost. Mario Quote Link to comment Share on other sites More sharing options...
big-phil Posted July 29, 2006 Share Posted July 29, 2006 Yah, what they said to the third power! Quote Link to comment Share on other sites More sharing options...
Thumper Posted July 29, 2006 Share Posted July 29, 2006 It is most likely a leak between the afm and the turbo or turbo to the tb. So I would check all the connections/clamps and all the hoses coming off the pipes. Quote Link to comment Share on other sites More sharing options...
