Supercharger help…gone back to stock??

Long story I’ll write more later

who is the resident supercharger expert?

If my 5.7 had a supercharger on it at one time but it was taken off the engine and put back to stock intake ,what would be the issues?

Would it run without any problems or codes?

What else would be needed? Stock injectors,fuel pump,or anything at all?

 

I won’t claim to be an expert, but the truck would need the stock injectors installed, the original stock tune (calibration), and ideally the stock heat range spark plugs. The larger fuel pump shouldn’t cause an issue, it will just return the excess fuel flow back to the tank. Not sure anything else would pose a problem.

 

Thanks. I’m researching as I am able. I am reading that the ECM is permanently flashed and can’t be undone?

 

If you don’t have the original tune file, I would think the dealer can flash their most updated file for your Vin if you take it in to Toyota. May want to double check that though.

 

What’s wrong with the supercharger? Where are you located?

 

Bought the car without it.

 

Fund out who flashed it if possible. They could have the tune on file. A long shot.

Another option is to talk tuner who did it, get a tuner box (my genius) to export the current flash and have them reverse it to stock using your host data.

 

Don’t know about the ECU yet. I’m pretty positive it had a SC at one point. Keith @dirtydeeds thinks so as wel.

here’s the codes and a picture of the injector colors. IDK what the stock injector colors should be.

there is a TRD intake box on the vehicle,and a supercharger belt diagram with smog sticker underneath the hood

no supercharger though

Do you have a pic of the intake box, does it have the little popper indicator coming off the top or is it the regular black and red TRD box? I’d also see what plugs are installed and how they look. I’ve seen stock, as well as aftermarket injectors including 650 and 750cc be that brown color so that color doesn't mean too much unless they were the green TRD ones.
