Agreed, they should be using the 55/56lbs injectors minimum as it's likely less than 700 otherwise.Yes, the engines are speed density, so not gonna gain much in the tune.
The roush tune is likely to make even less power as the kit states it comes with 35# injectors. Even max effort it will be hundreds of HP/TQ less if that’s the case.
It's the Magnuson blower that VMP sold before...nothing to do with the old Roush 2650willing to bet it'll heat soak as easy as the 2015-23 Roush superchargers did. no real reason imo to go for this over Whipple
