What's the biggest size I could get away with on a DD that will soon be a toy once I get a work beater? I won't be towing much of anything at most 3k pounds. I will be using the truck for a weekend warrior in the mud and at the strip and maybe if I am keep her together a few local at shows.
I know I'll have to change the rods because I have confirmed I have PMRs. And a BTS will follow shortly after. I'll also be swapping out my gears for a set of 4:56s and maybe 40s next time I need tires.
What supporting mods would you guys recommend with the injectors you list too?

 

It all depends on your power goals.

I'm running 250/200's on stock PMR's, stock pushrods, stock springs, and a stock HPOP.

In other words... it's not the size of the injectors, but how you use them.

Personally, I'm the type that would find out your power goals, and then get injectors that can support way more power than that, and tune them down to the level you want. That's what I did, and I wouldn't go back.

With these injectors, I'm running a 6.0L intercooler, 38R, BTS, 4.30's on 36's, home-made fuel system, intake, exhaust, gauges, and a few little knick knacks. This is a very reliable tow pig. I have yet to see anything pull harder up a mountain pass than this thing.

 

400/400 and a lot of $$$$$ for supporting mods to go with them.

Tune them to what you want and go.

 

I really dont have a "set" number but no less than 450 rwhp
