I haven't been here in a while. It looks like the N/A 328d is getting more exposer in the tuner world, compared to back in 2017. After extensive research, MY conclusion is that the top 2 tuners are JR and KermaTDI. JR is in my province and is only 1h drive away. However, it looks like the Kerma numbers are better. My goal is to squeeze out as much WHP and wheel torque (400 ftlb wheel hopefully) as possible. And, I also want to delete the SCR, EGR, DPF...Kerma does not offer a delete. My question is, can I Kerma tune for performance and use another tuner for just the deletes? Would I gain from the deletes (exhaust, DPF..) Is there a delete tuner that works well with karma stage 2 tune? I want to delete all emission and get most numbers while keeping it a DD. TIA to all!
