Injectors or Delivery Valves First

Can you guys explain why people say 7 holes are better for towing and then some say to just run 5 holes?

My plate and afc are already all the way forward. Is this the mod you are talking about doing?

Yep, thats the one. The fender washer mod and shortening the AFC foot adds a little bit of rack travel, and the mack plug adds a little more (on 160 and 180 pumps). A few thousandths of an inch doesn't seem like much, but it makes a huge difference in fueling.
 
Do you know what p-pump you have? Makes a difference in the way to get power.

I had the wastegate drilled to 1 inch and set at 26 to 28 lbs of boost on the 351. I'm just saying a lot of power can be had with out spending money on injectors.
 
Definitely do compounds if you're going to be towing with any kind of power....500rwhp and manners should be pretty easy. I'd say injectors first also.
 
just get a 100 ground plate and move it forward. that should bump up your fuel enough. if not get the rack plug
