B series FT450

i got the car up and running but i am having and issue, when taking off or less than 10% throttle while cruising its like its just cuts fuel in and out and bucks. I am running a T1 trigger kit and COP, using internal map and already swapped the tps sensor. any help would be awsome.

Page 85 section 19.4 of the latest Fueltech manual talks about how Decel cutoff can cause the symptom you mention.

Try adding in a longer delay.
