All the options are available for your model/year:

1. Diablo Delta two or three stage chip. Has a stock setting plus 1 or 2 power settings. This is the least expensive route, but has the fewest options. I recommend a 2 stage chip with stock and a 94 octane performance tune. Here: http://www.motorhaven.com/customer/p...tid=136&cat=37 -- I've programmed a ton of these.

2. Superchips Custom Tune chip. This is a 6 stage chip. Stock, 4 power settings (all custom tuned) and 1 kill-switch settings. I can program a wide variety of settings for just about any driving condition. Here: http://www.motorhaven.com/customer/p...cat=274&page=1

3. Superchips Microtuner. 3 power settings (87 octane, performance towing, performance no towing), plug-n-play, lets you change shift points and shift firmness. Has a basic diagnostic code reader. Here: http://www.motorhaven.com/customer/home.php?cat=169

4. Superchips Custom Tuner: 3 power settings that we custom program (just about anything you want), , plug-n-play, lets you change shift points and shift firmness. Has a basic diagnostic code reader. Lets you adjust air/fuel ratio and ignition timing. Here: http://www.motorhaven.com/customer/p...cat=274&page=1

5. Diablo Predator. Plug and play, several octane settings, adjust the shift points and shift firmness, upgradeable via web downloads, state of the art diagnostics tune, live data logging. This one is the cream of the crop for non-custom tuning from us (you can make you own custom changes if you want). Here: http://www.motorhaven.com/customer/home.php?cat=249


All will help with shifting. You don't need to make any changes to the transmission. Your best options for 94 octane are 1, 2, 4 and 5. Option 3 is programmed for 91 octane and doesn't take full advantage of 94. Sorry I didn't answer sooner... don't work the forums on the weekends.
