As per my other post my car is loosing power somewhere and I am trying to track it down. Can the inlet manifold on the turbo being clogged affect performance by say upto or more then 10bhp? I got access to the top earlier and got alot of soot / **** out of it however taking the whole manifold off looks a bit laboroued and I will need a good 1/2 day or more to take it off and properly clean it. I just want to know if this would help me recover some power. There was about 5mm-10mm thick in **** at some points but it is now clean at the end where the intercooler pipes and egr go into.
