Quote: I'm thinking it could be the K&N Air Filter as i did oil the **** out of it. the symptoms you describe match a severely blocked air filter oiled filters are meant to be very lightly oiled, paper is better anyway

I have replaced the Air Filter the next day with a Repco one and its still doing the same thing =[ Fuel filter was changed 2 months ago, can always replace it again i guess. Chances on a faulty 044? likely or they reliable? its brand new no more then 2 weeks old Gonna tow it to the mechanics tommorow hopefully maybe they can figure it out. but till the tow truck get there can always swap the fuel filter see if that changes anything Some original photos have not been recovered yet.

Sounds like a fuel issue, check int / ext fuel pumps, fuel filter and your rising rate pressure on your fuel reg.

only dose it on posative boost so basicly sounds like vacume under pressure problem mate. your not getting any + boost so it cant be trying to suck large amounts of fule because it dosent need. id leave all ur n/a stuff as is n go through all u turbo stuff as an N/A vl dose not have these issues at 40-60 km/h with heavy acceleration (simulating simmaler fueling requirements. ) my moneys on vacume pressure.
