Injectors

425-450 is pretty easy to get from stock injectors. It's the last 50-75 that stretches the limit on duration. 400 is a pretty "safe" number though
I guess looking at HP as the metric may be the wrong way to go about it. I would say PW and timing are more important. What numbers thay produce will not always be the same.
For me it's around 2800 PW and 28* or so. Beyond that I get scared.

LBZ stock is 365 horse. So you guys are saying you can only get an extra 35 horse from stock injectors ?

A puller isn't a bad idea but it isn't a "you gotta have it to do the job" kind of deal.
As for injectors, like others have said buy them from a quality source. My shop carries a few different brands to try and suit everyone's budget for most parts but fuel system components are not a place to "save money". We typically use F1/Flux Diesel, Exergy, S&S, or Dans for injectors.
LDS also sells a great product so you can't go wrong there either.
400 at the tires. I wouldn’t go past 2000 pulse if you like your pistons, sure multiple people get away with much higher pulse but there’s more risk.
So I'm seeing a 20% off coupon to order from auto zone online. Genuine bosch remans for 300.00 each lifetime warranty. Seems pretty hard to beat. But I might be better off with some over sized injectors. I need to build my trans as soon as possible and truck is going to body shop for work too. I cant spend 5k on injectors at this point.
If you keep it down and use larger injectors then yes, it should be easier on the engine. The tune needs to accommodate the injectors to reduce PW and timing to make them safer. All else being equal, 400 HP on larger injectors is better than 400 on stock
Just buy the AZ replacements and leave well enough alone. Just tell your tuner to keep PW and timing in a reasonable range.
Until you actually build the trans to handle the power, adding a lift pump, exhaust and tune will get you to about 500rwhp, which would make a very fun street truck for you. You shouldnt need any other mods at that power level.

I got the injectors Saturday. Spent a couple hours on the passenger side got those 4 changed out. Moved on to the drivers side and had 2 hold down bolts the were seized in. I hooked up enough wiring for it to run again and ran it till the engine was hot. Went after those stuck hold downs with spray and worked them back and forth snapping and popping quarter turn at time. Got them both out. The only injector and the driver side that was not stuck was 8 in the back. The 2 middle ones had leaking copper washer and a bunch of black death carbon build up holding them along with corrosion above the o ring. Ended up cutting a fitting off an injector line and welding it to a slide hammer to get 2, 4 and 6 out. Called local dealer to get new line and they had no clue told me a week to get one after i gave them the part number.
I believe you can also get those injector lines from LDS. I think they sell new and used ones. Maybe give them a try. And also don't forget to replace those hold down bolts so you can get proper torque on them and not have them leak like you saw
