My truck has a Roush supercharger. I wrecked it a year ago and flipped it. Only body work was needed, however there is now a huge power loss. No check engine light. All plugs and wires changed. At a loss.

Hello,

This could be a problem with the intake air tract leaking and not letting all of the air enter your engine. Also you might want to double check the air filter and Mass Air Flow sensor[MAF]/Intake Air Temperature[IAT] sensor and make sure that they are tight with no leaks.

This guide can help us find it

Please get back to us with what you are able to find out and we can go from there, if necessary.

Thanks,
