Boost on fiesta rst
standard boost is 7.2 psi.you will need to get a tuner to get your car to run higher boost safely as the fueling needs to be increased to match. you can run a bit more boost with standard parts but idealy youl need chip actuator and setup by a pro or it could be a ticking time bomb!!!!
You need a suitable remapped chip to start with before anything, if you try to raise boost now not only will it destroy your engine and experience overboost protection.
Stage 1 165 named so because that is the claimed power it's supposed to give, will be easiest as it just requires a chip and boost adjustment. This will see around 160HP + ATF on a good setup/engine.
Stage 2 is 195 chip again meaning the claimed power, beige denoting the colour injectors (701's) to be used. This will make around 170-180 HP + again dependent on engine condition.
