Not really,
The only settings that will effect spool time are AFR and ignition timing.
The more power you make off boost, the more exhaust gas you generate and the faster you will build boost, running very rich will also adversely effect power etc.
Remember that its very easy to get det as your turbo comes on boost, this transitional area where load is built at a high rate should be tuned cautiously imo.
But to be totally honest you want to be sorting advance out on a rolling road... is there one locally that you can hire for a few hours? and use your self...
