ok i have a 54 plate wrx which has had a vf34 fitted and should be running at 1.4 bar of pressure but this morning when driving it in the freezing cold weather i put my foot down a bit and the boost went to 1.5 bar of pressure? is this normal for it to go up a bit or do i need someone to fix this? if it needs fixing does it mean i need another remap as it was only mapped about 5 months ago? or can i do something to lower the boost.

 

A slight overboost is to be expected with how cold it is at moment, personally I would not worry about a 0.1bar increase as the map will allow some variance.

Did it go well ?

Agree with the above, mine spiked to 1.7 bar on the way home (-1 degree )
