car jolts in first gear

[JDSfastGN]

When ever I go from a slow roll or stop and WOT the car it spins the tires pretty bad, when this happens the car will sometimes act like its hitting a rev limitor though out 1st gear and buck back and forth. Basically the same symptoms as a motor torqueing over on the possitive battery cable, but my lights nor the radio flicker and all my battery cables have been rerouted to a safe place. My 02s read fine but this is via an OTC 2000 so the updates are pretty slow, ive seen 4 degrees of knock when this happens but most of the time im trying to keep it straight and not staring at the monitor. I'm running 15 psi on 93 right now, its new cr43ts gapped at .032, new delco 02, new delco wires, semi new coil pack, original module, re did all the grounds, new fuel filter. MAFs are pegged at 255, and fuel is fine as well. Is this the dreaded wheel spin knock? The car in the past before the last round of mods was fast and could light the tires at the top of 1st into second, but this is pretty hard wheel spin right now. It seems like a pretty violent buck like it just stops its pull and then re spools and takes off again. BLMs and integrator are all in the norm, i wish i could use a directscan and record the problem, but don't have one at this time. I'm gonna recheck the battery cables and the ground, as well as the alternator wire, to make sure nothing is touching. What else could it be, any ideas would be great. The car runs great from any roll and pulls very hard all the way through 3 gears once it hooks, i get no knock all the way though the run. The car has a poly mount and doesn't move too much, the tranny mount was doing alright a week ago when i put the tranny back in but i may have to look into that. Thanks for any help.
