Dynos do not offer the items you are listing, they just show torque, and HP, just like the G-Tech... It's all about gauges, and what's plugged into the OBD2 port.

I wouldn't trust an accelerometer attached to the car by a suction cup to report hp and torque accurately enough to tune with. Also, an autometer boost gauge isn't going to give the accuracy, and more importantly the curve vs. rpm, to tune boost. A wideband O2 will be useful, but again, it's not going to show the data over rpm... it's just going to show you the A/F right now.

As far as the features of the Street Tuner... it looks like the best you can do is datalog to a CSV file on disk that can "be imported into popular spreadsheet programs for display or graphing". You might be able to get the data you need to tune, but at the very least, it's going to be pretty tedious.

Like Mike said, you might be able to do some minor tweaks, but I'd be extremely wary about actually attempting to tune a car with the tools you listed. The biggest reason is that your data aquisition tools are not integrated, which means they may not be calibrated to each other, and there is a higher chance of human error when overlaying all your data points. For example: what happens if the G-Tech thinks 5500 rpm is what the Street Tuner considers 5300 rpm? And how are you going to record A/F ratios in order to compare them to the curve you're importing into Excel?

You're either gonna blow up the car pushing it too far, or get a result that's not as good as the result an experienced tuner with the proper tools would get. If you were to significantly improve your tune, I'd call it luck.
