1k hp guys help on set up i am getting closer to the end of my build and i am having trouble getting a straight answer to my questions i plan on making 1k hp to the ground with my set up 408 AFR 205 custom cam pt88 turbo.
now what pcm injectors i would like to stay away from a bunch of driver boxes do i need to go BS3 if so what is needed to do so
i have a 98 tank stumped
and planed on running a magna fuel 750 pro tuner pump
this is the kit but i am running a vic jr intake and sheet metal elbow also the car has a th400 rmvb.

96 lb injections, driver box and stock PCM will do it just fine.
they make a 100 lb/hr high impedence injectior now which does not require the driver box also, but its really short you will have to run spacers to make it all fit up.

x2. I also run a driver box, stock PCM, and 220lb injectors. It is actually less expensive to get a lowZ driver box and run lowZ injectors than to run huge highZ injectors directly from the PCM -they are much more expensive and arguably not as precise.

hit the nail on the head. i just got some 160's and after pricing them out it is 400 dollars cheaper to run a driver box. driver boxes are not hard to wire up at all.

What brand injectors are you comparing? It may only be at the larger sizes where the price advantage takes place. I have had zero issues with my AEM driver, I purchased it with the LS1 plug and play harness so there was no wiring/splicing/guesswork.

You will either need an aftermarket computer or you will have to fudge the tune. The 98 PCM is limited to 15 psi and I doubt that you will see 1000 rwhp on that combo by 15 psi. You will likely need 20+psi.
If you are going to an aftermarket PCM solution, then just buy one with the ability to run the low Z injectors. They are more precise. The aftermarket computers will integrate other things that you will need like a 2 step. So between a good 2 step and driver box you are at over $500 already towards the new computer. The downside is that the aftermarket computers wont run your stock gauges so you will either have to buy gauges, by a racepak or piggy back the stock computer.

my car is a 2000 i just have a metal 98 tank for stumping and i was thinking the same thing you are 98Z28CobraKiller about the 2 step injector drier box exc, really 1k hp doesn't matter i just want the car to run good and am not trying to buy parts twice 8.99 is my goal if i can do it with stock pcm that would be cool if not bs3 is what i was thinking
if i run the bs3 with racepak wold it still run my speedo and all necessary gauges i have heard with a race pack u need a 1500 harness to do so but i not sure i would love a racepak but i dont want to drop 6k on that and bs3

the 160# high impedance I got were a direct fit for an LS1 including the plug and the height. I wanted to minimize the chance for any screw ups.
We tuned it with HP Tuners 3 Bar Speed Density.
Idles fine, does not foul plugs at all.
BTW, they are 160# at 3 Bar and we reference 1 to 1 with boost.
Nothing against driver boxes, but I just wanted ot keep things simple.

I ran my 8.9 on the stock 98 pcm but I was fudging the fuel. With a 2000 PCM, you shouldn't have a problem. Switching to the BS3 would be a mistake for sure. You would lose resolution and alot of scanning capabilities and like I mentioned, your gauges. Unless you piggy back the stock pcm and then it's just a clusterfuck.
