E50 is about max on the stock system @ 11psi with bolt-ons before low side started dropping. Since then He installed a LPE DI pump and JMS booster then upped the boost. Have not had a chance to do any logs yet.

There are a few more changes under the fuel pump tab you can make along with the fuel pump minimum voltage that will squeeze a little more out of the factory low side pump. I was able to tune a Z06 that was dropping to 49psi on E42 up to e55 with the low side staying about 60psi.
You need to adjust a few of the KPA values and duty cycle in the fuel pump tab as well to overdrive your factory low side along with the voltage increase. Doesn't make much sense to increase the voltage past 15.5v though, the cars charging system will never make that much voltage. The JMS system is able to do a much better job. I suspect that with the JMS I could run full e85 on the Z06 with stock pulley but full bolt on. And could probably add a pulley and still run e50. |

Or add any pulley and run E-50. Ted.

E-30 was in a good place. I will say that I run .82-83 Lambda though. I suspect if you ran .88 lambda you could go there but I absolutely will not go that lean.

What about the JMS + Lingenfelter Big Bore LT4 High Side Upgrade + Katech 30%+ LT4 injectors? The goal would be to run pump e85 which is usually e70-e78 year round here in Florida. Then with a pulley I would think e50 should be doable as long as the low side can keep up. Agreed on the Lambda. I usually target .83-.84 for stock pulley cars and .82-83 for cars with a pulley. |

My fuel setup:
LT4 injectors LPE hpfp LT4 low side w/JMS I can run E45 @ a peak of 12psi boost targeting .82-.83 lambda. @ 10psi I can run E60. @ 8psi I can run E80. Low side is holding fine, I am injector limited. Thinking about grabbing some +30 FIC's, but even on E45 I can still run a decent amount of timing.

I have also done the LPE big bore, DSX Aux pump with +60 over injectors around 800 RWHP. Ted.

Could you run e85 with with a lt4 conversion on a lt1 if running lt4 injectors, hpfp and low pump with the jms booster?
