His user name is edvancedengines. Im sure he wont mind if you PM him. You don't have to have a traction dyno to get your car close. Drag racing isn't rocket science, just alittle common sense goes a long way. Keep it as simple as possible. Im sure hes going to get you to get those weights from side to side closer to the same.
good luck let us know what happens,
