I know this topic has been somewhat beaten to death, but I searched and couldnt find a direct answer regarding whether or not it was ok to use an inline pump with uberdata.

I just bought a slightly used Revhard kit stage2 kit for my 99 LS, and it comes with the 12:1 fmu disk, and an inline fuel pump. At this point, Im leaning towards just switching to uberdata right away, and not even bother at all with the fmu setup. If I decided to run uberdata with dsm 450's, would it be a bad idea to put in the inline pump that came with my kit just to be on the safeside, or would it run super rich with this setup?

Im also debating whether to just throw the FMU and inline pump on there for a while, just running 7 psi. From what Ive heard, this setup is generally pretty safe as long as you pull a few degrees of timing from the distributor, but I dont know if I even want to mess with the FMU at all, and just convert to OBD! and run uberdata right away, or just go with the hack. Any opinions on what I should do?

i would not use the FMU it sucks ***. BTW yes its safe to run the inline pump with uberdata. Just hook up a wideband and clean the a/f up. Read more about uberdata and inlines before you do ne thing though... check out the uberdata support forum.
