Hello everybody,

i would like to know if the programming of stage3 is different from stage1. I mean could i get more HP by replacing only the ECU?

I'm not sure for which compan of ECu your are talking about, but I do know that Speedparts Stage 1 and Stage 2 are the same ecu map. Stage 3 and stage 4 are the same ecu map. all other costs are the cars hardware upgrades that need to be done to effectively take advantage of the increased power.
