Slant 6 Turbo 68Dart Project
what do you have the wastegate hooked up to?
with the mechanical advance slots closed to around .301 you can run 10* initial. the .301 will give you 8* mechanical advance. the vacuum advance will be over 18* and drop pretty much as soon as the boost comes on. if you are running 0-1* the 10 initial should help quite a bit with drive ability and spool.
sounds like you need more accelerator pump action going on. check the clearance between the arm and the linkage. should be next to no space in there. it should start to piss as soon as you move the throttle. may need to look into a different cam. they are color coded. if you look it up you should be able to find what you need.
