Which is easier to hook up in my car, DS or turbolink. How much more useful are these tool over a scanmaster. Will i be able to tune my car just like i was on a dyno if i used one of these tools, to show me where im lean or rich and where the hick ups are in my car? i have the scan master but right now my problem is i think in fueling which i can really only guess at without being able to record a run and look at some graphs. Are graphs created on DS or Turbolink, which is better. My combo is listed and im hoping for high 11's on radials. Will it show me boost levels too?
