Right hi guys, apologies in advance, my English skills arent the best so I'll try make this as clear as possible.
A basic description of my car, bought it standard and turns out its mapped as I fitted gauges and found it was boosting higher than stock, since buying it I've done a fair few mods to the car ready to bring it upto a "stage 2" figure (minus the fmic) I wont bother listing the mods.
The problem I'm having: so it's temperamental as far as I can tell, when I'm driving and go to accelerate fairly hard my boost spikes to over 2bar, sometimes hearing some sort of chatter from the engine bay, I have to lift off and slowly accelerate back on again to get boost. This happens most times.
Other times the boost gauge gradually rises but cant feel the power change, sort of feels like it's leaking out the system and leaving me with a flat feeling with no boost
A few times before but not for a while now its felt like it's gone into limp mode, not boosting over somewhere like .4 bar.
Apart from that the car runs sweet, bit rough on idle but heard it's normal for these engines.
I've had it smoke tested and it showed no leaks! Ran diagnostic through it and it's not pulling any codes.
Had a few suggestions as to what could be causing but was hoping someone on hear may have had this issue in the past and know where to start? some say it's the map, others say the lamber sensor, others say different.
Getting on my tits now so any help would be greatly appreciated!
Thanks guys
