Stage 2 cars - Higher power cars will see faster turbo spool and some power increase of around 3-5 bhp. This is very hard to prove on a dyno on a stage 2 car. Stage 3 cars - A turbular manifold is a must have for any stage 3 Fiesta! The standard manifold will be finding it hard to release the air with the manifold pressure not being able to cope wit hthe power. A tubular manifold has a massive increase in air flow which could see big gains compared to standard.
