Hi Guys
Have the following problem if anyone can help

EF motor in xf with eb dizzy
was running eb ecu with bbm cable tied- good power, free revving etc

installed EL ecu to utilise BBM ,
have low power when climbing up through the revs, feels like handbrake is on
did resister trick to auto ecu, checked all pins at ecu for voltages - correct
re timed to 0 degrees, idles perfect, exhaust note does sound a bit hollow.
have vacuum for BBM directly off manifold tree with one way check valve in line, BBM activates when revving via throttle body.
I have 1 or more leaky injectors internally, injectors used are bosch 0 280150726.
could i be unfortunate enough to have a crapped out fuel pump not dishing up enough fuel as well as suspect injectors causing something like this? Maybe the EB ecu could handle it a bit easier than EL?
Have new spark plugs also

Thanks in advance if any one has any suggestions

I've sorted it, wasnt waiting long enough to go into base timing mode, it was retarded, or the person holding the timing light was
