Bruno, the best thing you can do for your car is to get it on a rolling road with someone who understands your engine and carburation. There is no formula for which curve is best, you can only put it under load and see what it does, then adjust accordingly.

Www.tdcperformance.ca has graphs showing different curves for engine specs.  Also instructions on curve selection.  Hope this starts you in the right direction.
