Default Better buy

I'm getting some money soon and I was thinking what would. Be a better buy for cost and hp gains. 5x14 injectors for 475$. Or full cut dv for 275$

Buy them both dvs are relatively inexpensive just make sure you research what will work best with those injectors I would say go with. 022s the fuel hard without the heat buildup you get from 191s

Yeah. But they said it'd be ok if I wasn't heavy in the pedal. And I don't tow anything except for a small four wheeler trailer maybe my cuzzins small buggy once in a blue moon

Right on. If it was me, I would go with the injectors. I think you'll see the biggest increase there.

imo, injectors. I installed 370s with stock 181s and it was a good gain and was impressed. I got some .022s and installed them and im even more impressed on how they smoothed out the 370s. I have a set of 7x.010s to install when i get the truck back together.

The 7x.010 are comparable to 5x.014. There is a big thread and argument on another forum about the two different style of injectors. Along with flow charts for many sizes of the 5 hole and 7 hole sticks.

Which injector would be more reliable and fuel efishant. I mean yeah I know there a decent hp rating but would one or the other give u and problems. Like low end popping or stutter or anything of the sort
