Right I brought a Scooby and having problems with it
1. When first brought car was hitting boost cut because was running standard boost solenoid and some one had fitted a manual boost solenoid in same pipe work so put back to standard and started spluttering when building up boost
Also had equal length manifolds removed and fitted standard manifold that's when I noticed the most

 

What model and year?.

 

W reg turbo 2000 I have fitted a 3 port boost solenoid thinking faulty soleniod and no better so fitted just manual boost controller and still splutters and feels slow
