Hi all, haven't had my gtir long so this is the first problem I'm having with it. It normally boosts at 0.9 bar running a mine's ecu with exhaust and air filter being the only mods. However yesterday it's developed a strange problem. It's only boosting up to 0.5 bar under full load but when It reaches 5500rpm it then changes to 0.7 bar :/ so far I have cleaned the plugs they're all ok, took apart the MAF and cleaned with brake cleaner, unplugged the ecu in an attempt to reset it incase it was in safe mode and blocked off the dv to see if that was releasing pressure. Checked for boost leaks aswell with no results :/ abit lost as where next to look can anyone shed any light on this for me?
Cheers Marc.
