No, there's plenty of fuel for a 66. Only thing more fuel would do is get you to about 700hp instead of the 625-650 range and it would spool up faster

Maybe with a huge correction factor/generous dyno. 700 on stock fuel takes a damn perfect setup. Only legit backed by track times was Mike D (dyno 720ish) and trap was 695 with HPs.

Thats hard to say.... Obviously you'll lose spool up with a 66. On stock fuel I'm not really sure that a 66 will give you any more power than a 72mm drop in would do. If it never tows and is not a daily driver, although people do daily drive this, bite the bullet and go with a 72mm single. I believe people run them on stock fuel with success, and it'll make more power then a 66 or 72 drop in. Worst case if its too laggy for your liking, you can sell the 72 and just swap it for the 66 with little to no modification. It all depends on what you'd rather have.

A drop in 72 does not give you a 50-75 hp gain without a billet hp. A single 66 will. Single will reduce or get rid of the need for an external gate. A 71mm single is not recommended on stock fuel IMO. Too big to work. Although some people have had mild success in regular cabs with stock fuel. But they are much lighter and easier to push.

Stock pump only have enough fuel for 600-650 max depending on the dyno and how healthy your pump is. 700 on stock fuel is basically a fluke or a freak.

That was my point regarding stock fuel....you said it a lot better.

It's pretty good. Had to try a few different tunes before I found a good one that would spool decent. It's laggy but not too bad I imagine once I add some nozzles and dual fuelers it'll be a lot better. Yes it's 67.7/74/.90

We recently Installed a H&S Performance Single kit on our 6.4L. Zane and everybody at H&S Motorsports did a amazing Job on the kit. Spool up is just as quick as the stock twins, and on the top end there is a noticeable increase, where the factory twins fall off, this turbo keeps pulling.

Overall the truck is a lot more fun to drive, with more fuel I see this turbo picking up quite a bit more power. And let's not forget the sound....

I have no doubt this truck could tow 10K easy and plan to regularly.

I will get it loaded down this weekend and see just how it does, along with some more videos, both loaded and unloaded.
