Fueling issues. One of the reasons why it's pre set

Gretchen has tried a HPFP and the tuning in that didn't work bc that would be ideal or an boost a pump But now on his LFX build he's shooting the fuel directly into his intake like a port injected motor...

The injectors are fine like I said...but there's a reason why people like Gretchen tried using a HPFP..

From all of the reading of various FI builds I've done on this site, the HPFP on the LLT appears to be "maxed-out" something north of 400RWHP (like lscamaro posted earlier). I'm no expert by any means, but I think that's going to be around 8 - 9lbs of boost. I think other HPFP were tried, as well as alternative lift pumps, but they weren't successful. Tuning was always an issue as well on the LLT builds. Keep in mind that both of Gretchen's builds as well as others on this site are trying to push the limits of what's possible on the LLT/LFX platform. He's at over 20lbs of boost now. That's not generally what you'd want to do for an reliable street driver. So IPF has taken the conservative approach (smartly for a mass-marketed system, IMO), and pre-set their system for 6psi to avoid being anywhere near the LLT fueling limits.
