TBI conversion bogs bad when cold, log included

[SV1000]

Normally I don't stab the throttle when the engine is cold but I noticed when I do, it almost stalls. Eventually, it coughs and sputters until rpm gets up a bit and then it runs. Gradual throttle to the floor does not cause any major issues.

AMC 258, manual trans, no egr or knock, no vss.

I attached a short log to duplicate the bogging issue and an earlier log with a lot more data.

I would appreciate any feedback I can get.

Thanks!
