So I was wondering if I could run flex fuel system on my 2021 Camaro lt1 which is procharged with d1x head unit. I currently have lt4 High pressure fuel pump and lt4 injectors and was planning to get dsx flex fuel kit. You guys think will it work or I have to do more fuel upgrades?
Some people said I should also get DSX AUXILIARY FUEL PUMP KIT.

Thank you

Without some sort of low side upgrade it would be pointless.

Puddin is right, get the Dsx low side and you'll be able to run maybe up to E50 but you'll have to keep an eye on the low side pressure so to ensure the high side doesn't start falling off and running the fuel rails dry. What ever percentage you can run is better the 91 octane which is the highest California has. You could also look a running a boost a pump to bring up the voltage for the low side.

I see , So I just purchased the dsx flex fuel and I guess gonna get the dsx low side also. I see some cars they do straight e85🤔
Also you think it's possible to run meth and E together ?

Thank you

Boosted cars that are running pure e85 usually have some pretty serious fuel system upgrades. I would stay away from meth personally if you plan on using it as a fuel additive. That's just one more thing to go wrong and then you'll be back here asking how much to replace a short block.

Ahahah I see, well the question is my tuner told me to go meth injection with 50meth /50 water and basically its gonna help to cool the car and get better timming but stay on 91 if do meth. But I feel e85 is just feels much better for the car.
