Hi all, I have a recent problem with my car. When I accelerate in 2nd gear, at about 2k up there is like a judder/ hesitant with the engine(like a kangroo in the car). There is no loss of power or excessive smoke, just for the whole rev range above 2k it holds back once on boost. It does it above 2k and up. I have used the search button but could not find anything.

Thanks for your advice

first thing to check is all the rubber boost/intercooler pipes for any splits or loose connections.
