Where did you get this information about the BE table? This is the first I have heard of it. Tuning your afr based off the map makes much more sense than tps and/or rpm on a turbo car imo. I never had any issues on a centrifugal set at 759rwhp.

My own personal findings and there is info posted about it on the hptuners forums. I have lots showing cars being well into boost yet the boost enrichment fueling isn't active it has a delay even when setting the map kpa low. It's best to setup your desired afr with the pe table.

Very interesting. I am just now tuning my first turbo setup. It was a non issue with the blower.

I am going into PE very early on, the problem is the lean spike and the lag in between commanded AFR and the AFR actually reflecting the change. I have read where there can be latency issues with the wideband.

I am just not sure I want to drop an additional 4 credits converting this over to another o.s. to get transient after I've already spent 4 credits on this.

very odd... i have my primary pe table set at 13.2afr out of boost and boost pe table set at 11.5. there is absolutely no delay with the boost enrichment, does just what it is supposed to. never even touched the 105 kpa enable map.

i have never touched my transient fueling at all. There is still some more work you can do before you have to commit to that.personally i still believe your problem could lie within your injector data. have you tried entering smaller amounts in the VE table instead of just throwing 20% at it? try increments of 2 or 3 and slowly work from there to see if it improves. real time tuning would make this very quick.
