Thanks for the response. 15-20 whp right?

And yes, if this is in the wrong section, please move mods. I figured, it'd have more visibility here, and also since I'm talking about hp gains overall, maybe it'd be fine here???

I never did a baseline however.

holy moly... 310whp from just G3 and HFC, and using stock CBE?!?!?!?! wow.

Question then, since I have my CBE now, if I go with the G3 and also go with say, a Berk or FI HFC, would I need a tune to run all 3 mods?!?!? Or can the stock ECU run it safely?
