Im kinda concerned about running the car with the fuel pressure drop on low side. Especially with cooler weather coming, and more fuel needed at colder temps. Already riding the line.

I am looking at lt4 fueling, but wondering if there are other things i can do for the short term. Been trying to learn about the fscm and whether or not there are tweaks i can do there to band aid things a bit until i get the lt4 fueling. Am i going to need to unlock that anyway if i install lt4 low side pump?

Heard about others using a low side fuel pump voltage booster to make things better, even if its not a perfect fix...

Today's agenda... install the 3 bar map and do some more logging. Going to try a few more ignition timing tweaks, and increase the PE. Watch the fuel pressure.

Anyone know of indepth info you can pointme to about switching to lt4 fueling? I think im going to need the 8 injectors, high side pump, low side pump. Ive also seen mentioned about replacing the hp fuel supply pipe whenever injectors are swapped?
