performance chip help please

1100gs 1995
I have had to remove my performance exhaust to have some work done to it ,so have fitted the original exhaust, taken out the jumper cable and refitted the original beige block and replaced the K&n filter .The problem is that she running a bit lumpy when running at steady revs so do i have to take the tank off and change back to the original chip or is there another way by changing the position of the jumper leads
Thanks in advance

I would probably say you need to put the jumper cable back in and set it to stadard exhaust map.

Try resetting the motronic . It may run Ok when it's been done. Ignition off - remove fuse 5 - ignition on (don't start the engine) wait 10 seconds - ignition off - refit fuse and take it for a run.

That'll be the same law of nature that says you only need to take a sticky dump just after you've had a shower .......

It's just to remind you that you're not as powerful as you'd like to think.
