Any way to fix the issue with a tune..? They are not performance injectors just stock upgraded as far as efficiency.

Just installed the Bosch 3 injectors on my 88 245 n/a.. idle and throttle response has improved tremendously. Unfortunately it now seems to have a pretty rough idle on cold starts.. after u give it a little gas and warm it for a short period of time it smoothes out and runs like a champ.. any ideas ...
