Finding a chip for my build

Yes I know, beating a dead horse. I’m planning to push high 300s and Maybe tap 400 with my 94 940 wagon. Engine is 94 b230ft, forged rods, arp studs, ipd cam, stock intake manifold, custom exhaust manifold, he351 with a billet wheel. My buddie and I just found the limits of the 440s with a hx40, turned out to be around 19-20psi. So I’m gonna need bigger. I’m planning to go with Simeon deka 630s and I already have a 4 bar fpr. I don’t think the classic Swede chips will worm because they call for 470cc injectors, I do have the 3in amm. Let me know your guys thoughts:)
 
I don't think anything like that exists. You'd have to do something custom. Any chip you buy will be scaled for a specific injector or MAF, along with being tuned for a particular engine setup just in the way a stock chip would be. There's a guy in Sweden I think his name is Dänn Westfält who might be able to help. I haven't seen his work so can't necessarily vouch for or against it but he does seem to get good power out of LH2.4.

Is that 400 at the wheels or the crank? Maxing out 440cc injectors even aggressively is probably 300 hp.

Right now you have a collection of parts... from what I read, I gather those parts are currently assembled more or less into a redblock... your redblock... you don't mention the condition of said redblock, whether you're using the stock cast pistons, stock gapped rings, etc, whether you built the block or slapped a bunch of parts on it. Regardless, if you want those parts to remain inside the redblock, you need some information from 2024, not 2004.

First, running your imagined power levels through an online injector calculator using pump gas (I assume 450 crank) requires a minimum of 788cc/min injectors with 80% duty cycle... changing to e85 pushes that to 1103cc/min. Different calculators give different numbers, but YMMV.

You're going to need reliable engine management. If you're going to do this with chips, find a reputable tuner in your area that can strap your car to a dyno and tune it. If not, roll your own with any of the capable aftermarket ems installations... but again, for maximum longevity, pay someone to tune your car on a dyno.

The stock cast pistons are pretty stout, but won't tolerate abuse for very long at all... especially if you didn't gap them a tad bit wider.

Agreed, we maxed them out on my buddies car, probably around the 300 mark

Did I not tell you my engine build? Forged rods, STOCK pistons, arp studs, ipd turbo cam, I’ll probably just end up going stand-alone tbh, doesn’t seem like 400 on lh2.4 is worth it
 
For this year I’m gonna run classic Swede stage 3 chips, and lime 25-29psi of boost, enjoy the wagon for a while with the power it makes on lh then possibly convert it. 650cc injectors should get me where I want to be, worst case methanol injection is an option.

Do you have the guys email?

As suggested above. You need to run the injectors that the classic swede chips are designed to work with. So if that is the injector for the stage 3 then sure use them. But if it's not you want to use something close to that rating for the chip.
