[urq] 3b upgrade suggestions.

[James OBrien]

    I have a 84 ur quattro with 3b installed. I want more power(don't we all).   I've seen  034efi  has turbo, and injectors but they dont have software update.  2 Bennett has all of it.  Has anyone tried these, or gone another route.
   I am trying to get as much reliable h.p. as possible without putting in new pistons and crank. Is 400 hp out of reach?I have stainless header and "951" intercooler. Any btdt, recomendations or suggestions?  
 Thanks in advance for your help!    Jim
