Gentle eh?



I wouldn't waste time with just dyno'ing it, as the dyno is only a tool to confirm and test changes (and in some cases, theories).

Getting a professional tune done in person, with both road and dyno time, is the "procedural" way to handle it. Were you to be building a 800hp road monster, this would become absolutely needed.

In general stock swaps don't require the same level of detail, since very few things are changed from a factory calibration, however if your experiencing a problem related to the trans cal, a mailorder tune will just be guess-and-check'ing the results.

By taking the truck to a pro tuner, the time on the road and/or dyno should be able to reproduce your problem and view it on a log. Then make the needed corrections based on the log and general driver preference.

You may be able to find small gains in performance as well, since even bone stock motors have 5-20hp laying available in minute timing and fuel changes.
