I understand. Currently, the only mods I've done is the "change driving habits" one. My current actual mods budget doesn't exist, thus my inability to progress in that direction. Sounds like the first thing to budget for would be a ScanGuage since I don't have one yet. From what I've understood, is a ScanGuage functionally an after-market "trip computer option" for a minivan?
Yes it does that plus its a real time readout of most of the engine sensors as well as calculate instant mpg(its most important feature). It will also retrieve any error codes in the ECM.
