Good evening, I have a Leon FR, auq engine I want to do stage 2, I have an exhaust of 70-63.5 with a free catalyst, 200 cells, 4 bars for and tIP, and I am thinking of changing the wastegate forge or putting an electric boost controller, which have about the same price? The goal is to keep 1.1 in the redline or even 1 bar and over I don't want more than 1.5bar because reduce quickly the lifespan or k03s
Won't I get a better constant pressure range with the boost controller? I don't have money to buy those together so I want to buy one of this but I don't know what is the best choice
