Hi all I'm a newbie if you haven't guessed lol Iv got my self a T plate Golf Gti Turbo Iv been told its been mapped but no recite its got FMIC very big , (440CC Injectors and walbro fuel pump) So iv been told lol and also a K035 Turbo my Qs is ! ...... can you tell if its had all these also what PSI should it been running if standard as at the mow it boost to 12psi and then drops the high the rev is this right ?

[Dalo Harkin]

yes itll boost high and then tail off
unless you look at/take the parts off you can't tell
should be getting more than 12psi though - has it been mapped?

[Wazzzer]

440cc injectors will probably be green, you should be able to see them if you take the engine cover off.

12psi isn't much boost at all for that setup

mines doing that without any major mods and ive just replaced the PCV system and added a piper cross panel filter
