I just purchased a Pulsar unit and would like to give my feedback.
Pro's: The speedo correction is nice function.
Con's: I did have to lower my tire size from the tire manufacturer specs a little bit to get it spot on.
Pro's: MDS shut-off is a nice feature
Con's: It does not keep it off all the time like others have stated. I don't care for this so I go to manual mode with gear selector
Pro's: Throttle response is changed between modes which is nice. ECO = Lazy, Stock = Same, Tow = Med, Performance = Super touchy
Con's: None really
Pro's: Tow and Performance modes you can feel a difference in the mapping. Throttle response, timing (it will ping without good fuel), traction control (it spins tires easily in Performance mode). In ECO mode throttle is lazier and I am recording almost 1 mpg better but more time is needed to truly tell.
Con's: Really none here as all options are good IMO with a piggy back unit.
Pro's: Adjustability between modes is nice.
Con's: I can't make mine do this on the fly. I have to put the truck in park in order to switch modes. Not sure if this is in an update or if I am doing something wrong.
Final Verdict: It's an easy decision for me as it is a good purchase. The under $500 is a no brainer as I tend to blow more than that on other stuff not as cool.
Next step for me: In discussions with Jay Greene to custom tune. Will probably go with a separate PCM so that I can go back to Stock easily. I did this with my 2012 Challenger as at the time the security was an issue to tune and then later was handled easily. If I learned anything from my 2012 Challenger these guys will figure out how to work around it and the costs will go down as time goes by.
