your cranking rpm setting should be just a bit higher than actual cranking speed. when you have it up too high its running off the cranking rpm settings. your pulse with is too lean, i doubt the injectors are even opening at .2ms. try richening the ve table, try something like 10-15% at first. also your pw spike might be your acceleration enrichment settings causing that.

autotune works well for getting the table worked out out of boost. once i get it worked out there ill shut auto tune off and estimate a ve table for in boost based off what autotune has done. id also recommend roughing in a timing table before you go too far, its going to change the ve table far more than you might think.
once you start boost tuning, it gets hard to street tune something of this sort of power. myself, id really recommend seeking a dyno shop. its safer for both the engine and you as your able to load is to parts of the table you might not see under street tuning conditions.

Yeah I'm incredibly happy!
Right now its basically just drive it around and get a few miles on it. My main focus is to have it at the show Sunday. It runs pretty nice up to about 25% throttle so I'll likely putt around with that back and forth to work this week.
It'll definitely be going to the dyno for tuning, we've always done most drivability and rough performance tuning on the street then to the dyno for the real deal. Right now though power tuning is at least a month away.

The tune is getting better, still rough as hell. I think this thing is going to spool the 6262 as fast or faster than the vg30 spooled the Holset. On the way to work today I gave it a little more throttle and at about 2800 rpm heard the thing starting to whistle. That of course pushed it up into a stupid rich cell and it fell on its face lol no boost was built mind you, was still at 2-3 in/hg. I've yet to achieve 0 let alone positive pressure.

Just a little demo of my Nexus 7 and Shadow Dash MS. The speedo is slow right now because I'm using GPS. Later on when I figure out how to wire my vss into Megasquirt it'll be real-time as well.
