better but not all good yet

alright Ive been posting for ideas on whats wrong with my car. Got my tps adjusted and that helped ALOT. Im gonna try a AFPR and resetting my computer by disconnecting the battery for about half an hour then connecting it again. My problem is when I floor it my car takes about a second, then responds. After it kicks in it pulls pretty hard and rpms move pretty quick. Heres my setup 89 t/a full exhaust system (headers to tips) 52mm throttle body k&n filter tb bypass accel wires and accel coil. Repair shop said it might also be my distributor. Any other ideas? thanks yall helps alot

whats your base/total timing at? Does it bog, or does it just not respond at all, is the module in the dist the original? I have a feeling its possibly timing related
