I'm ready to upgrade my ECU and I like the BSR product because it allows me to return to stock programming easily. I'm having trouble however, understanding weather or not the stage one settings are ideal for my car given the mods ive already added. I have the GS intake, the 3'' DP, and the Preformance Exhaust already. Is the stage one BSR agressive enough given my mods. I cant understand if the only difference in the "stages" are the additional hardware or if the actual ecu is programed differently with each stage.
