droozels Posted April 20, 2014 Share Posted April 20, 2014 Hi I brought a starlet gt the other day and I was told by the person that sold it to me that it was all set up to boost at .9 my problem is it wont hold .9 it over boosts to 1bar up to 1.2bar and nothing will control it first tried was the profec b by turning everything down no difference still over boost then disconnected profec b so we could go back to stock boost settings still over boosting, then an adjustable actuator was fitted tried on a few different settings same thing was happening........anyone got any ideas that we could try would be much appreciated.....mods:front mount intercoolerfull exhaust system decatfuel pressure regulatorfuel cut defendermagnecor ht leadshks bov Quote Link to post Share on other sites
akyakapotter Posted April 20, 2014 Share Posted April 20, 2014 If it's still ct9 will be a cracked waste gate and your getting boost creep Quote Link to post Share on other sites
droozels Posted April 20, 2014 Author Share Posted April 20, 2014 yeah its still ct9 cool will have to try and pick up a second hand one and give it a go, thanks for the reply Quote Link to post Share on other sites
akyakapotter Posted April 20, 2014 Share Posted April 20, 2014 Take the cat / decat off look for cracks just port out the wastegate Quote Link to post Share on other sites
droozels Posted April 20, 2014 Author Share Posted April 20, 2014 Nice one cheers for help mate Quote Link to post Share on other sites
Liam_D Posted April 21, 2014 Share Posted April 21, 2014 Cracked wastegate wouldn't cause that much boost creep. It'll more than likely be the decat and no real management. Is it still internally gated? standard actuator? Quote Link to post Share on other sites
droozels Posted April 22, 2014 Author Share Posted April 22, 2014 Liam yeh still internally gated and it was running stock actuator but changed it to adjustable once fitted took it out for a couple of runs still same issue then took it out for some fuel yesterday journey to petrol station same but on way home it felt differant and was holding boost all the way home it was fine which I thought was strange im not going to be able to get out in it again until tomorow so I will check if its still behaving or not Quote Link to post Share on other sites
