Hi

I want to find out if my 03 WRX blob has been mapped so I fitted a boost guage.

I have read that stock turbo should boost to 0.7 bar? Is this correct? I am hitting 0.9 bar. What pressure can i expect to see if it has been mapped?

I have a greens filter and turbo back Prodrive exhaust fitted but am not sure if increased airflow affect turbo pressure?

Many thanks

 

normally if its been mapped you would be hitting 1.2 bar ish, o.9 is normal i think.

 

+1 for that, 0.9bar is standard pressure mapped would be around 1.2/1.3
