Do you have to run bigger DV's with bosch 370s?

 

absolutly not. they are 2 totally different things and you have 181's in your truck right now which can be worth over 800 HP. leave the DV's alone for now.

 

Why would anyone run 370s in this day and age? But no you don't need delivery valves.

DVs will give ya lots of smoke and high exhaust gas temps.

As a drop in yes but if the pump has been bench tuned , a dv is just a calibrated component to achieve desired flow in which case the egt control would already be planned for.

Alright thanks I was just clearing that up because I have been told that before and didnt agree with it either. They are just a cheap 5x.12 with wrong spray pattern unless they have been remaned. Im up in the air about getting injectors or not.
