Ok guys heres a breakdown of my customer ride 6.2 block trickflow heads cnc 230cc 427 stroker kit 45# injectors slot style maf fast intake stock fuel sytem N/A car long tube header no cats texas speed comp cam short travel lifters cam spec is .618 lift .228 duration thumps good! I have car on dyno question is why does this darn car no matter what I do I even removed maf wire out of connector and disabled in tune turned the dtc to show maf or check engine light the car runs lean on starts if you keep it running it will throw check engine light car will free rev and the stf trims start changes and your god to go no matter what I have tried it has to do this before it will run right im stumped I even tried bumping up max delta and same thing I figured worse case tune it VE and the darn car has to go into something like what I call limp home but its not limp home at all check engine light wont throw on start up even with maf wire out until it does this cold start up any help would be great thanx! I have verified proper fuel pressure smoke tested intake checked headers for leaks we degreed cam so timing is spot on base wise im stumped!

found it goes into a maf failed state in datalog?

Is it a Speed density Tune? Post the tune file and any logs you may have.
