who told you that
the flow rate of the 55lbs siemens and the 403 bosh grey are almost identical
and we can map for either
if you have the right spec and make of t38 and the right engine spec it is easily possible to max out both the siemens 55's and bosh 403
for these instances we recommend the siemes 83lbs which I have in stock
