i thought an update was needed after so damn long.
the turbo is going strong. VERY strong. im running it on 14psi daily. might hit 18psi a bit later but i havent been bothered opening up my bonnet for a few weeks after all the time ive spent under it lately!
i've sold my SAFC and was getting around 380/tank with the tune i had. on the standard computer im getting 430km/tank which im finding strange.
anyways, the reason for the long reply was i had a few oil problems. i did my valve stem seals, fixed up the pcv and its all running sweet.
also because of the n1 oil pump im using which pumps 25% more oil ive been told, ive made the reducer 4mm as to not flood the turbo.
im going for the greddy ultimate so ill be back with results after im finished with all of my uni work and exams are over (i know ill spend too much time on the car if i get it before!).
