this is only a 3rd gear pull... I'll run a 1-4 gear later this afternoon if the rain goes away.... Pretty glad I went with the JMS, I thought my pump was failing.

Now @ 5998rpm
AFR 12.1-12.3
low side 76psi
rail 2900psi
inj 5.4 ms

E64 fuel stock LT4 fuel system @ 7.8PSI... It's looking like I can actually pulley down to 10psi... but im already at 619rw... dont know if i should push it more car is running so good.

So for future people reading this post... the JMS is definitely worth it.
Change your Logging channel back over to Lamda and tune for .82 you can be too lean because when you take a EQratio and convert it to AFR in the channel the software assumes gasoline with no ethanol.

Lambda is the same across all fuels.
