I find the stock 3.43s are terrible for launching, reason is they are to easy to bog or burn, there is that sweet spot they like, but its hard to overcome if you miss it! I feel a 3.90-4.11s would make launching easier, letting you launch at a lower RPM and having the engine do more work and getting into the band faster.
