6.0 swap hard to start when warm
6.0 swap hard to start when warm Been driving my 6.0 swap Impala for about 2 weeks now. 6.0, small cam, truck intake, walbro 255 in tank pump, vette regulator, -6 AN fuel line, stock 8.1 injectors(34lb at 58.5PSI)
Issue i am having is when at operating temp, the car is hard to start.
I have checked Fuel pressure when warm, and it is correct at 58 lbs, same as when cold. I have also used brake clean to check for vacuum leaks and none were apparent. Temp sensor is also in working order as i have a gauge readout Via the Torque app.
Once started, the car seems to run great, just will not start without a little throttle input from me when warm. It will crank and hit a few times but won't actually start. sometimes it will start but kinda stumbles up to a run. If I hit the throttle while cranking it still cranks a bit longer than normal but will fire up pretty well.
any suggestions on where to look next?

Yes, Tuned by ShorTuning 2 weeks ago, Issue came a few days after the tune. day of the tune, it fired right up as it was started at-temp many times throughout the tuning process, a few days after however, it will only start with slight throttle application when engine is 150* or above. 150* is nominal at this point, as it is the coldest i have seen the temp gauge and still had the long crank time/throttle needed to start. Cold start, or even about 100* it will fire right up almost first revolution of the engine.
