I am very close to buying a 2011 GT with 2.3 TVS supercharger. I plan to add a few more mods, thus will need to adjust tunes as I progress. What are you guys using for DIY tuning? I want something that works with my Windows 7 laptop. I'm not interested in handheld tuner.

I'm aware that a bad tune can very quickly wreck an engine. I had a big-block Camaro with Accel DFI and I tuned that one without too much trouble (after I got a good base tune from Accel). But that was 10 years ago, I'm sure the newer tuning programs are much more sophisticated.

I'm a relatively conservative tuner and driver, so I just want to be able to do some data-logging and make adjustments as I swap parts in (or out). I'm actually hoping to find a tuning program that can make adjustments automatically as I drive around at varying speeds and loads.

Many thanks, Dave F.
