I think 15% nozzles and a 66mm would be pretty fun.

I wouldn't waste your time, and just get custom tuning.

Well the custom tuning will be just pulling back the pw in order to try and maintain 24-25k. Really IMO if you can't run a race sized pw with 24/25k rp then nozzles aren't worth it, there's other ways to get the power you're looking for without compromising the already questioned reliability of the stock pump, and pw for rp
Sorry for the misunderstanding I am NOT interested in upgrading any part of my fuel system til the truck is closer to paid off lol. I'm just trying to get the best mileage possible and reliability. I just wanna turn the tune down if I can't keep rail pressure up due to a weak or failing pump. So I was curious so I can check next time! Thanks
On Performance if you can maintain 24-25k at WOT your HPFP is probably pretty healthy.

My friend Andrew's truck (buck russell on here) has stock hpfp and just a fass with 30s and a 466. Truck made very high 600s. Pretty sure he holds rail pressure decently, but would have to ask him. Either way the truck runs great and is a blast to drive. He is upgrading to dual pumps soon and more fuel but its always ran well with the stock pump.

His truck has custom tuning to maintain.
Custom tuning is going to benefit the OP too. I personally like the idea of running a larger nozzle and tuning around it rather than trying to max a smaller one out. Obviously a 15% nozzle would be considered "larger" for a stock pump, so that applies here.

Yea im.running matt at gear heads tunes. ...so do you think I could run a 30% and tune down or you think a 15 is better?
Jeff@Spartan

Either. 30% leaves you with room to grow.

If it can be tuned correctly I'm all about going 30's but if it's going to destroy my stock pump I don't won't to go that big

I wouldn't think so. Might want to give him a call or email him to verify. Matt is an excellent tuner and I'm sure he's messed with a similar setup before.
I asked that very question to Matt before my truck went under the knife and at that time, he recommended just going with 15%. That was 6 months ago and tuning continues to evolve so maybe his opinion has changed, but in December, he said 15% so that is what I went with.

Meh, stock nozzles at 2.35, 15% at 2.1 or 30% at 1.8..... As long as it's tuned correctly for the nozzles to maintain FULL commanded rail at wot your not going to loose any power. If you can maintain full desired rail, and use all cc's of fuel the pump can deliver with less pw, it will have positive effects.
The problem is that no one actually spends the time and live tunes these to get the desired result for their individual pump/truck.
