DavidAshton Posted July 6, 2009 Share Posted July 6, 2009 Cant see how the front mount would cause this, chances are you have knocked something fitting it i would think, do the usual check plugs and leads etc. Do you have an acurate boost gauge, sure its not fuel cut? You done a diagnostics check? Quote Link to post Share on other sites
mattgtt Posted July 7, 2009 Author Share Posted July 7, 2009 hay yer its new! everything was fitted correctly checked many times, its at about 10psi on my gauge when it starts to cut power. cheers Quote Link to post Share on other sites
Steve GT Posted July 7, 2009 Share Posted July 7, 2009 firstly is the engine management light on?if so get a diagnostic readingonly other thing off the top of my head is on the pipe going into throttle body part near the inlet theres an outlet to fit a dumpvalve too. is this blocked off correctly. e.g Dump valve, blanking plate etcif not there might be a leakthats all i can think of Quote Link to post Share on other sites
mattgtt Posted July 7, 2009 Author Share Posted July 7, 2009 yer got my hks ssq on there and is working correctly and there is no light on! cheers Quote Link to post Share on other sites
iamlegend Posted July 7, 2009 Share Posted July 7, 2009 boost creep or fuel cut mabys Quote Link to post Share on other sites
Curtis Posted July 7, 2009 Share Posted July 7, 2009 try reseting the ecu it worked on mine and my mates skyline, disconnect the negitive terminal on the battery and put your light on for a couple of mins to drain any excess power out the system Quote Link to post Share on other sites
WallaceGlanza Posted July 7, 2009 Share Posted July 7, 2009 Its probably fuel cut, what kind of boost gauge is it as it may not be completely accurate. Plus the level of fuel cut can vary slightly boost wise from car to car as its triggered by the map sensor voltage.The symptoms you're desribing are fuel cut though so I expect its that.

mattgtt Posted July 7, 2009 Author Share Posted July 7, 2009 hay mate its an autogauge but its spot on because i work on aircraft and when are gauges get checked i bung it in for a quick accuracy check and its fine! but bit of progress found out its creep followed by fuel cut so now making a restriction for the airfilter jus tested it and it seemed to solve the problem because im only after a temp fix til i get new engine and fuel setup, turbo etc Quote Link to post Share on other sites
