shifting at 6500 rpm and it was tuned just for a safe tune to drive it back home 70 Miles but my tuner said he needs more time with it to get it right since we only had like an hour of tuning time

With that setup you should be shifting around 6800-7000 rpm. Even still your trap speed should be higher. After you get a proper tune, if it still runs similar speeds I’d be pulling the trans for a health check.

White smoke is not good and typically means a coolant leak i.e. head gasket failure, etc. Does it smell kinda sweet? I would check your coolant level in the reservoir to confirm a loss of coolant. Did you do the head install? if so, were the block and head surfaces completely cleaned prior to installing the new heads and were new gaskets used and heads properly torqued down in the proper sequence? I would not drive the car until the culprit is determined and fixed because coolant can mess **** up. I would suggest dropping the oil to see if its milky due to coolant contamination.
Edit: look closely and see if the white smoke has a blue tint to it. I recently had that and turns out a few of my valve stem seals lifted off the guides. If no blue tint then it's coloant related more than likely.

I just went through the blue smoke at idle deal myself. I’d pull all plugs and see if any are fouled and replace if so. If any plugs have oil on the threads pull the valve covers and look at the seals on those cylinders. If you have single springs should be easy to see the seals. If you have duals like me you may have to remove the springs to assess the situation. Could be seals that lifted up and/or smashed valve stem seals.
After that’s resolved I’d have the tune touched up and then see what the car does at the track.

It's partially tuned and smoking and you're asking us why it's slow..
Pretty obvious what the problem is, at least one of the problems.
Tune it, tune it right, get it all sorted and quit raggin on it till it's done right or you'll create more problems or pop that motor.
Cmon man, this isn't complicated.
