I have a 2015 cupra 280 SC, no mods other than jb1. Later turbo type. Just ran a data log via my jb1. My ecu is only requesting max of 12 psi - about 0.8 bar. I did wonder why the car felt slow. Car is in stock trim, no idea why the ecu requested boost so.low, car feels like it has no turbo at all. Running 99 ron fuel. Any ideas?
