Hoping that someone can help.
Problem 1 is cold start problems. When it started up the car starts as you would expect the revs go to around 1200 - 1300 however within seconds the car drops down to around 500 - 600 sounding like its about to cut out. It does this 2 or 3 times and then idols back at 1200ish until the choke is off. The car does hunt slightly and when the revs go up you can hear the turbo whistling and dumping. I have recently fitted a badger 5 tip open ended filter, forge 008, n249 bypass and a new MAF. This happened before I fitted all of the above.
Idol control valve? Air leak?
Problem 2 is a boost problem, sometimes the car doesn't feel as quick as others. Its REVO stage 1 remapped but when you put your foot down it feels like it doesn't get going till higher up the rev range, other times the boost feels like it kicks in much lower down and harder which I presume is normal. The only way to describle it is more like a n/a engine. Also the car sometimes double dumps, but its a totally different noise to what the forge makes and when it does this the on boost sound is different. When I fitted the badger 5 a couple of the pipes that go from the top of the block into a round plastic valve (excuse my lack of knowledge) are very soft.
Could that be the problem? Air leak?
I presume the 2 faults are linked and its looking like the car is going to have to go into the garage for a smoke test but I was hoping someone else has had the same problems so I could take alook at it myself.
Any help would be great.
