Finally fixed my slice but where did the distance go?

So I have one of those moments last week.  I was playing with a friend from work who I have never played with before.  My general partners and I have a similar swing, out to in or straight with the resulting slice.  this guy had a massively layed off club and his bad shots would hook.  Epiphany!  If I lay the club off my slice will go away.  After 3 trips to the range I have a really nice straight shot and can actually shape it left to right and right to left when I want.  This is all really new to me so I'm still getting use to it and happy to finally have some options.

But my question is where did my distance go?  I could hit driver to about 250 in the air with a 20 yard slice to the right.  Now I'm getting 220-230 with a straight flight.  My swing still feels "odd" and I don't feel comfortable "swinging harder".  When I get more used to swinging around my body instead of up and down will the distance and speed come back or did I just fix one thing to only break another?  Honestly I will take a straight shot that is shorter and never look back if I have to.  Also, my iron play is now a bit off.  My long irons are better but 8, 9, P and G are digging holes and making contact before the ball.  I think I can fix the irons but the distance thing doesn't make sense to me.
