2020 V4 Arrow+Filter running issues

Two ten daily said:

I have a 2020 v4s with upmap “no db killers” but have the db killers installed on the exhaust instead, previously it didnt have the db killers on the exhaust and i feel like theres no bottom end power all mid and top. its loud especially when you are driving it. I dont think i have to spend another $ for a map with “db killers” i think the combo is perfect “no db killers on map” and db killers installed on the exhaust. I have the new generation arrow slipons too.

The dB killers help with low end power on the v4.

Hello,
With flash is there any difference if i use db killers or not? Do i need separate map then?

With Deussen, you can use it with or without the DBs. With T800, you have to pick one or the other.
