Hello all, i have been working on a SBC with a twin turbo set-up for 14psi, i currently have a Holley stealth with 950 pro injection set-up with narrow band 02, this is the set-up i was running when naturally aspirated worked great. I added turbos 55lbs injectors and 2 bar map, now i have been unable to get the engine running right, running real rich smoking etc... I have been told a wide band 02 is required for tuning any forced induction engine. Holley make a wide band add on kit, however i have also been told that Accell DFI genVII is a better set-up.
Has anyone run the Holley 950 with boost? is that the right way to go or convert to DFI?

Thanks for any input.

Thanks JND
