Bad Luck w/ fresh blown motor

[Z28Rider843]

ok, my Trans Am has been in the shop since april
just got it back Friday
TRW forged pistons, lt4 hotcam, bolt ons, 3000 stall, Vortech S Trim Supercharger
So i picked it up got tags, insurance, etc.
I havent got it tuned yet, im going too
but i have drove it about 70 miles and now its acting retarted...

It all started when i bottomed out on some railroad tracks, my buddy behind me said he saw sparks and something skidded across the road, turns out it was a bolt, idk what it came off of. After that, if felt like a it needed a transmission mount, it gave a thud shifting from 1st to 2nd, ok, tranny mount, not a big deal

But then im on the way home, i eased into the throttle just to try to get an idea of how much power i really have....then after that i let off and its sounds different, i turn on my road, and it sounds like its skipping and sputtering....today i cranked it up, and let it run, its pouring black smoke and time, and other times white...and smells like gas really bad...its not a clicking and clanking coming from the motor, so hopefully no warped vavles... I think its just an O2 sensor or something and the air/fuel mix is all fucked up because its untuned... and I know i need to get it tuned asap...

Any ideas? or help?

First thing, check for an exhaust leak, or cracked pipe from when you bottomed out. That's where I'd start. Second, Don't even think of rolling into the power until you get it tuned. You could EASILY damage something beyond repair internally in the motor if the tune isn't there.

once i find out what it is, its getting fixed and not moving till its tuned

True, True. You've got balls man. No wait, you're absolutely nuts. Without it being tuned, I wouldn't even do anything more than idle it, let it warm up to bleed the coolant system, and drive it onto a trailer for hauling TO A TUNER. I had a solid base tune, and I was scared to do anything more than idle mine when I started it up for the first time (383, F1A procharger). It freaked me out just getting it driven up the ramp into the trailer. Again, you're nuts. Not trying to make you worry, but I would not be surprised one bit if you had internal damage.
