How much boost are you running? Pit Bull chips are notorious for bad knock. Hopefully your new chip will resolve the problem. I would dump some xylene or race gas in and see if the knock goes away.

one thing i just thought of

i did put a powerplate in after the tranny install and after i installed it and went for a drive i had knock and could tell it was retarding the timing could this be something maybe to remove and see i was going to wait till after the chip came in and if it did not fix it take the plate out

.....

and as far as boost gooes it is set on the act for 15 and thats all i get on the guage.

There's no reason I can think of that would cause the powerplate to cause knock. The reason I send to dump some race gas in is to tell if you have knock from running too much boost for the octane you have, or if it is false knock. If you up the octane and the knock doesn't go away, it's false knock(ie. downpipe hitting frame, etc.).

Are those #s you posted for BL and INT(113 and 108) your #s at WOT? If so, that says you're running rich. O2s are OK, but they are only as good as your O2 sensor. You could be getting rich knock.
