Gtr Boost Problems

[#taylor#]

hey guys i've just purchased myself a r33 gtr and havent been happier, but now im starting to have a few problems related to the boost.

every so often the car will be running full boost (near the 7 on stock gauge) and suddenly it would just drop down to just over 3 and stay there and wont go back to normal.

it has me stumped and really starting to get to me. last thing i want is problems on a new car i've just bought.

its a stock gtr with a cat back exhaust, pods and a pair of bovs.

ive checked all the cooling pipes and lines

no smoke blowing out exhaust or oil in cooler lines

checked the cat

changed the fuel filter

put a hks evc 5 in and got rid of standard boost control(which boost line is the in and out also?? the one with the yellow line)

and i still cant fix the boost problem

any help would be much appreciated thanks
