2007 XC70 184,000
My BMW 2.5 NA had g/s of 3.8-4.2 (per jfoj) my XC 70 is in that range @ idle in park however under a hard pull the XC70 registered well over 155 g/s. Being new to turbo is this normal? I swapped in another MAF and experienced similar readings!

I searched and found that possibly leak at the turbo might be the cause?

Could this be because those with NA engines were in the range of mid 20's g/s as was my Bimmer!?
