JB4 is most advanced tunning box on market. So if real remap is not option then go for JB4.
This is my
Cupra 300 with JB4 + Stage 2 hardware(downpipe, exhaust, intercooler, air filter, modified intake, HPFP before I change turbo to bigger one)... Stock is realy not stock and is only JB4 turned off but still with Stage 2 hardware installed...
