Just got a rebuilt and now am boost later need help

Ok i just got a rebuilt and been driving the car my daily driver now so the car was running good boosting really fast but know it doesnt boost has fast when i give it gas it kinda feels like it wants more gas or the turbo is lagging all i remember doing right after that actually is a day later i was going to sift after leaving a place i missed the shift and kinda redline it i little but i dont think that would have done anything right?

WOW! That is some sentence.
Redlining the car for a short while will not hurt anything.
Is the engine rebuilt, or the turbo?
How is the idle?
If the turbo was recently rebuilt, the bearings may still be tight (if it has journal bearings), it will boost more quickly when the bearings loosen up.
If the engine was recently rebuilt, there may be an exhaust manifold leak or the engine is not fully broken in (making optimum compression).
I hope this helps a little.
