2019 Mustang 5.0 Return Fuel System Tuning

[nummbr7]

Have a 2019 Mustang Bullit 5.0 , with a Fore innovations L1E kit (single regulator)
Anyone have any suggestions for changes needed on these cars to go return?
Also PSI?

Thanks

That's a single regulator set up, depends on how you want to run it

- Static 70 psi
- 60 psi on boost only reference(no vacuum)

You could do lower pressure but you dont want to go too low, HPFP stock tables dont like running less than 58psi, part of why you dont use vacuum reference. So 60psi with boost only reference works well and keeps amperage down during DD conditions

ended up with 4.38 pulley about 15.5psi. Just barely could get it to make 754hp on pump 93, got it back on the dyno yesterday with ms109 and I was able to get 863whp, these cars are crazy

Those are some really good numbers. How much timing did you have in it and what was your lambda? You might be able to get more than 863whp out of a 15psi set up. If you have the octane for it, you can usually get away with 20-21* of spark and .79-.80 lambda(hoe ever I'm not sure what blower you have either)
