if i had a eaton ide be in boost all day and have an empty pocket book due to gas consumption.the novi is the best of both worlds when you want it.
its a catch 22.....any motor where you go blown the fuel consumption is going to suffer. However think about this.
ur going to want gears in a centri car and that will hurt gas mileage
in a PD car u dont need as steep a gear cause u make boost early.
So they kind of negate each other. Honestly id say do what u want and can find a deal on. I have a vortech S-trim and have had NO problems with it. Its an older unit it aligned perfect the first time and makes 433 to the wheels on 10psi and a conservative tune.
I may sell my vortech v2 s trim with after cooler
