Are the fuel tables the same for TBI a 383 stroker and MPI/Mag 383 stroker Engines ? I'm getting a ecu tuned.

Just thinking out loud I would say no. MPI with 8 injectors or TBI with 2

If your asking do they have the same exact fuel curve, no. Bob at mefi burn cannot provide unlock codes either for a mefi3 350 TBI fwiw so IF you want to tune one, you'll need a different base tune and tweak it till its close, fwiw, Smitty

I reached out to Whipple. They will build the new tune off the base file to what the 383 with the TBI needs.
