I'm aware of performance management devices (e.g. diablo, hypertech, bully dog, etc.), but I'm not looking for these type of devices. I'm looking for a device to assess/track my truck's performance (e.g. horsepower, fuel economy, 0-60 speeds, etc.) before and after making performance modifications.

Does anyone know of any devices that serve this function? If so, can you recommend a particular device/company?

Welcome to the club. What type of truck do you have, year, model and engine?

I have a totally stock (for now) 2010 Yukon XL with 5.3L, 6-speed trans.

I like OTC diagnostic tools. There more money than some others but they do alot more and as they get older you can get them serviced. Also make sure you get one than does engine and transmission diagnostics.

Thanks for the OTC reference. Are you familiar with which of their tools handles what I'm looking for? Long story short, I plan to do several small performance upgrades and I'd like to track how much each one helps. Thanks again for the input.

Bump. I checked out the OTC tools, and there more for troubleshooting diagnostics - i.e. a mechanic's tool. I'm looking for a device that captures performance data (i.e. HP, MPG, etc.). Thanks in advance.

Just found the Hypertech Hyperpac diagnostic computer. Anyone have experience with this tool? Accuracy? Worth $500?

can't the trinity do all of the recording stuff plus it tunes your truck as well??

You make a good point...most of the after market tuners capture performance data - right? I don't need the tuning feature as I intend to use Bear's tuning services. Bear uses EFIlive...suppose I could go with EFIlive - just seems like more complexity than I need. Thoughts?
