No in road trim it's a restricted engine so to speak as such it only runs 0.8 BAR (10 PSI) maximum, stage 1 raises this to around 15PSI and everything else stays standard, beyond this you need to change the MAP sensor to a 3 BAR item because you are now running more than the standard 2 BAR item can see and of course a software calibration to suit (Remap) Remember the atmospheric pressure is 1 BAR and so in reality the standard item can only see a BAR boost as you are now running more boost you need to provide fuel for it, as such the injectors need uprating to higher flow rate items (Typically Bosch green injectors or as of late the Siemens 55LB equivilants.

Btw if the injectors are standard they will be yellow.

The exception to the the above is something knows as a "Gunship" conversion, other companys do the same thing as well, this basically allows you to run near stage 3 power on an otherwise standard car by running a higher boost pressure.

It's not just a case of bolting on hardware, I would strongly advise you to drive it GENTLY to a tuner ASAP otherwise you could end up damaging/melting the engine!


One things a given, that is it isn't the standard software! If it was then fuel injection is cut at 7000RPM or 13PSI boost (Hard cut), even remapped software should still have a boost cut which you don't seem to have!

Do you know the chip thats fitted?

Also something you can easily check is to make sure one of the hoses either from the compressor housing, or to the actuator have not come off/split, as this would run infinate boost!
