Jim* Posted May 10, 2013 Share Posted May 10, 2013 When I put my foot down it will come on boost and sit at 0.3 and ill only get two green lights until 5.5k revs when it then goes up to 0.6 and pulls harder, I'm running stock ct9 with stock actuator.Anybody know what this could be?

Socks Posted May 10, 2013 Share Posted May 10, 2013 Boost LeakLeaky Dump ValveWorn Turbo Actuator In That Order... Quote Link to post Share on other sites
Jim* Posted May 10, 2013 Author Share Posted May 10, 2013 Can't be leaky dump valve because it is blocked off Can't imagine it's a boost leak as It was doing it with the top mount intercooler on and still doing it now with my front mount on Does that mean it must be my actuator?

micky boy Posted May 10, 2013 Share Posted May 10, 2013 Try another actuator sounds like the diaphragm is fucked on your stock one Quote Link to post Share on other sites

Jim* Posted May 10, 2013 Author Share Posted May 10, 2013 The wastegate does have a slight crack in it but its very small ill try getting a new actuator Quote Link to post Share on other sites
Starbo Moorley Posted May 10, 2013 Share Posted May 10, 2013 mine used too hold .9bar then spike too like 1.2 after 5kBest thing you can do is get thst motor ran in bugger of the ct9 and get youtsrlf a nice externaly gated td04 setup . Quote Link to post Share on other sites
H_D Posted May 10, 2013 Share Posted May 10, 2013 i would also check the turbo, thake the intake pipe off the turbo and see if you can spin the intake wheel. it should spin freely and should not have any resistance. Quote Link to post Share on other sites

Jim* Posted September 21, 2013 Author Share Posted September 21, 2013 sorry for bumping up an old thread but still needing help on this, have replaced my actuator, that didn't fix it, have taken off the turbo and checked for shaft p[lay and there is minimal play less than 1mm. and I'm 99% sure it isn't a leak from my intercooler pipework. does anybody have any other ideas what could be causing this? getting so frustrating now!

Addymk2 Posted September 21, 2013 Share Posted September 21, 2013 Checked your timing? If everything else is ok that would be my last resort. Both dizzy and belt. Quote Link to post Share on other sites
Jim* Posted September 21, 2013 Author Share Posted September 21, 2013 Mike at tuning developments built and fitted the engine so I don't think tht timing would be the case either Quote Link to post Share on other sites
