Avery - we picked up maybe .03-.04 so far with small tweaks in limited runs but the safety factor as others have mentioned is worth the investment X10. We've found lean spots in the tune-up that have slowly been ironed out so the engine is happier everywhere in the run (burnout to stripe). Our tune-up will never be perfect, but a data logger allows us to intentionally "chase hp" with far less guess work.

I think there's likely a benefit with consistency as well as you can slowly improve each aspect of the combo and get it all into a healthier spot. Having ample data really accelerates the development curve since you have empirical visibility to so many more things that are going on during the run.
