[ba] tweaking the Bosch CIS, is possible?

Say Guys,

Is there any type of "chipping" or whatever available for the early 
80's CIS injection? From memory I'm thinking that these are pretty 
rudimentary systems and that the chipping stuff didn't get started 
until later in the evolution of fuel injection.

If that's not possible is there anything to be had from a K&N filter 
and a larger capacity exhaust system or am I just kidding myself?

Thanks for any tips/advice.
