UPDATE!!

We got on the dyno and did 4 pulls before we had to shut it down. The LT4 fuel pump was throwing an error code so we had to abandon the tuning session for today. Tomorrow we will be pulling the top off to re-check the LT4 upgrade install and sort the gremlins.

The good news is that even with all the issues, the Esky still managed a best run of 634/847. That was on low boost and barely any tuning done. There still should be a lot left after we sort the high side fuel issue out but I'm good with those numbers if I end up being stuck there.

The attached video is of one of the runs + the dyno chart of our best pull.

did you end up with a cam in this thing? the 30%+ fuel lobe is one of the major reasons its needed. and its on pump 93?

what did you do for the low side (in tank pump)?

No mods to the internals at all. For the low side I installed a Armageddon 465 LPH fuel pump.

gotcha - 465lph should do 750-800hp pretty easy
and yea a 6.2 thats 11.5 compression with 10lbs of boost is going to make a ton of power lol if that torque reading is right he prob got out of it cause hp would have been real close to it when he gets the tune nailed down
i wouldnt do much more on 93oct, the DI you can get away with a little bit more than port injection

Holy Torque Monster!!! Look how flat that torque line is. It's hard to tell from the graph photo or maybe I'm not reading the numbers along the bottom right; But what RPM are you at peak torque and HP?

I bet it's a blast to drive!

A/F looks rock solid and where it should be. Not bad given the fuel problems.
