Yes... laptop tuning IMHO... has no substitute..... for example..... your scanmaster collects 2-3 datapoints during an entire 1/4 mile run.... where Directscan... gets up to 18 datapoints per second.... and I am sure powerlogger is similar... that's 225 or so datapoints in a mid 12 sec run.... you can easily see air/fuel ratios....RPM's.... see where the shift occurred... etc.... see the RPM drop every shift.... It really helps for tuning....
