What about your vehicle other than fuel pressure is radically different from Vortec TBI Van cal?
BLM issue you talk about is also part of $58 and is very difficult to tune out in that cal. Trick I use is to try and tailor AE to deliver slight extra shot of fuel after decel conditions. Have to work carefully with MAP and TPS AE to make this work and it never works as well as it should because stock $58 just doesn't provide enough control over AE. But the strategy should work better in the 7427 cals as there are more AE parameters to work with IIRC.
