Hey guys, I'm a little confused. What does this DP fix exactly do other than keep the DME happy so I don't get a code cuz of the catless dp? Will it change my fuel ratios to keep the car running normal?
On the BMS website it says you don't need this is you have a JB4. Well I have a JB4, but I keep it on map 0 most of the time. So I think buying the DP Fix would be good in my case?
