Hi everyone - I was wondering if anyone here has any thoughts/experience with this product. I'm basically looking for basic engine performance data that isn't already available on my dash...so I can take care of issues before my engine actually explodes. Okay, so I'm probably being a little dramatic. But I've noticed that some of you have this installed and was wondering if you are happy with it. What do you (and do you not) like about it? And for the rest of you - what do you use, and are you happy with it? I apologize if this is a subject that's already been discussed...I tried doing a search but only got limited results. Thank you all in advance for your input!
