Ok so I'm old school and I'm still running the bullydog but I'm seriously considering the smary jr. I would like to hear from those who have ran both to see if it is really worth the extra expense of buy the Jr. I tow 10K a few times a year and commute, I don't abuse my truck but like to have the extra power there when I need it. Am I going to see enough of a difference as far as power, economy, lower EGT's, and perhaps rail pressure (all the things the smarty jr. claims to bring to the table)?
