welcome to the site mate in respone to your qs it says there is a high/low boost setting - is this just a switch and can you change the amount of boost it boosts at? yes indeed it is, if you have it pressed in the car boots 0.5bar, if u depress it, it is 0.7 bar, its supposed to make it safer on less pleasant weather days apart from a filter and exhaust, it seems pretty standard - what would you recomended mod wise would be the first mods as such? id get used to it like that first, but most people tend to either go for new alloy wheels and new shocks/springs or coilovers, u may also wish to change the tmic to a fmic ive read about boost controllers/turbo timers?? confused as to what they are? a boost controller, allows u to see set quantites for how much boost u want to run, not unlike the button above, but u can choose your own settings, a turbo timer is hooked into your electrics and allows the car to continue running after you remove the key for a set time to allow the turbo to cool down - as very hot to cold will lead to problems also is a blow off valve same as a dump valve? yes the same, the car as standard comes with a recirculating one, whic most people change to a venting type
