So, I'm gonna pay him a visit n see what he can do for me...
Ill keep u guys posted, and thanks for the input.
P.S. Blueshadow, as for the ecu stuff, I have a chipped P28 that i did myself, so that's already covered, I just wanted to know about Uberdata and the associated components.
Later,

We are all saying the same thing, but just wording it differently.
Even though an FMU is not the best setup, at least it's predicatable and tried and tested. The reason it's not a good setup is it puts a lot of strain on your fuel system and injectors. To be able to supply enough fuel an inline fuel pump is needed and of course the FMU. There's in tank and inline pump, but you want an inline pump if you are using an FMU. A wideband setup on a FMU wouldn't be entirelt pointless. You can still use it to monitor your AFR's and if you see it going dangerously lean under boost, you can let off the throttle.
Now if you already have a chipped P28 then you are pretty much ready for Uberdata or Crome. On thing you can do is solder in a $9-$10 cell phone data cable to be able to datalog through your ECU. Now if you are lucky those guys you talked to have a wideband they can hook up to your car. From there all they have to dois make a basemap on UD or Crome, and start adjusting your fuel based off of your actual AFR's. The only things you'll need for your fuel system are some injectors and an intank fuel pump. A set of DSM 450's can be found for $40-$80 used, and a Walbro 190-255lph pump can be found for $79, $89 or $99.
The good thing about UD, and Crome is they also allow you to change your timing while in boost. With an FMU setup you either have to manually mess with the dizzy, which is not the best idea or you have to get an MSD BTM or something. And of course you can adjust your fuel in boost and vacuum at any RPM. With UD and Crome you can also adjust your VTEC x-over point and a few other things.
