Another question I have is regarding the switching points. I believe the ecu switches from low to mid trim at 100hz and then mid to high trim at 175hz. I have been using the the recommended switching points which are a lot different then the stock ones. I belive the low to mid switch point is around 44. Where should my points be?
also what are the differnences between tps enrich and boost enrich?

What VE table are you running? The lean spike, is this happening on shifts or just at launch (or in neutral?) What are the other response settings?
The low/mid/hi points in the pro are in KPA (manifold vaccum) not airflow hz, you can't correlate them that way.
TPS enrichment is based on tps movement, the TB size crowds the effect towards the light throttle end.
MAP enrichment is based on the MAP sensor, as is the boost enrichment. Which one is used is based on the TPS position. MAP is light throttle tip-in, Boost enrichment is stomps and heavy throttle.
Do you have a log of this happening?
