Boosting problem
Hi. I have turbo 2000 on a 2000 plate if boot the car it boosts fine till hit 4000rpm car stops pulling and judders until hit 6000rpm then goes back to to boosting again. I have checked the turbo and checked for any air leaks and that's all fine. Fitted a new maf about 3 months ago. Any body got any idea what could be. Been told could be lambda sensor??

I have similar issues with my boost and after reading the fault code it shows faulty lambda sensor but until you just said it I totally dismissed it, didn't think this would have caused an issue with boost ?

Thing is that rev range is usually when the engine is at highest boost, once past 6000 it is more likely that the boost is tailing off. The higher boost will blow out the spark if the system is not up to scratch. One thing to do would be to take it through the rev range on light throttle whilst driving so the boost is not as high and see if it runs okay, then repeat on the same stretch of road giving it full throttle to see if it runs crap. Having done a low throttle run then a full throttle run on the same stretch of road will tell you there are no speed cameras just in case you accidently exceed the speed limit whilst testing. LOL

Also check your air intake to turbo pipe these usually split
