got the car dyno'd and not happy with results, but the car hesitates at low rpms, such as starting from a stop light and up a bit, then i can punch it without problems. my list is below, and i dont know what is wrong. i was told i have an exhaust leak, and that's getting fixed when i get my LT's, but could that have made such a difference and caused the hesitation? I doubt it's slippage, I'm not going wot from a dead stop.

no codes yet, no vacuum leaks, i've had too many problems with that, so i check that everytime something is done to the car, and smoke? theres black smoke out of the exhaust, but it's supposed to be running rich, so i dont think much of it.

if you can see the smoke your running to rich
you should get a wideband a/f see where your a/f is at
if you were tuned they shoulda left you with abotu 11.8-12:1 a/f area

11.6 to be a little safer
but you wont see black smoke
