Is anyone running either of the following in their streetcar?

Racepack digital dash: http://www.proracestore.com/index.ph...sourceid=GPPRS

AIM MXL: http://www.aimsports.com/products/mxl-chooser.html

Would like some feedback on people who are running these setups. Pros and cons. I just think its a lot simpler to run a dash like this. Gets rid of all the extra gauges and gauge pods. Thinking about going this route but would like feedback of the good and bad for a street car setup and occassional autox.

Thanks
