Not too sure where you are coming from m8 :confused:

As Tom says if you have the fuel pump fitted, all you have to do now is fit some sort of boost controller wether mechanical or electronic and turn the boost up a bit. 1.4 bar boost on your Ralliart ECU will see you getting around 350+bhp
There are two types of Ralliart ECU as well make sure you have the none Group N version :)

got sports ecu for rally ra420996r1 why am i leaning out on ra and ok on standard then interpro are in bristol
You mean your fueling is running lean???

Thats the correct ECU that you have there. It should allow you to run richer with an uprated pump and higher boost without fuel cutting. Cant see why it would run lean as std though, shouldnt do :confused:

here is a graph of my 6 running all the stuff you have and more with boost @ 1.35

Not sure what your doing wrong....but I've found no problems running lean.....infact.....my problems are mostly running slightly rich, which I've been told is normal on the RA ECU.

im running the RA ecu setup aswell and also run a tad rich on the overun, i did turn my fuel pressure regulator up a little to run 1.5bar though.
Maybe your regulator is broken and so supplying a less pressure to the injectors
