Thanks to the forum admin for this thread and members for submitting your results.
I suspect that I may currently have an intercooler restriction.
Based on the data in this thread, I have collected some data to compare the Monza coolers with the Plazmaman types.
It was formatted very roughly so sorry if there's any mistakes.
Intake legend: 1-stock, 2-XR8/F6 Spec box, 3-Growler type or equivilent, 4-turbo side, no battery relocation, 5- turbo side - with battery relocation
Exhaust legend: 3/3.5/4-full system in this size, HF CAT- high flow cat, STK- stock
