We have found that 6th Gen fuel systems both low and high can have some variance so both need to be properly monitored. 700 rwhp and 640 tq “ish” will be approaching the fuel limits for sure, but remember that all Dynos do not read exactly the same. A 90mm pulley will yield approx 15 lbs of boost / restriction peaking at 16 as the 2650 keeps on going, with the larger snout, throttle body, CAI and no cats.
Here is a thread with data on the old Magnuson 2300 as well as a similar 2650.
