I just like the process of e tuning, I learn quite a lot through it and my driving style improves as the tune improves or changes. My absolute threshold for little changes in the car lowers as well.

If it isn't included in a "pre dyno" package with an e-tune, doing a compression test and a boost leak test are essential. I would also suggest cleaning your MAF as I always see them produce better readings after a good cleaning (only use MAF or electronics cleaner).

If you have a boost leak, the whole tune will be influenced and you'll likely need a full retune after the leak is fixed. In addition, boost leaks are very bad for turbocharger health as they lead to you overspinning the compressor/turbine wheel which causes undue stress and extra wear on the whole turbocharger unit.

Compression imbalances in the motor can also lead to similar tuning inaccuracies. Even worse, if you have an unhealthy motor, the additional power from the tune can cause things to go south very quick.

I would recommend changing plugs during the compression test, and making sure you have oil that's got plenty of life left before starting the tune (fresh preferred).

This is all good reading!!

So I see mainly suggestions for up and running motors, but what about those that have a newly built motor? Obviously to start you get a basic map from the info that is provided to the etuner, but my main concern is this...

Some say (and have proven to be successful) that giving the motor some stick for the first 20 miles is best, seats the rings and completes the final finishing process on the cylinder walls...some say its not the best and to take it very easy, then there comes the other part to that which I hear...don't go into boost for the first few hundred miles on a new turbocharged motor...kind of hard to do the first part if that's the case.

So what is the real solution on a new motor while being etuned?

1.) Don't run too rich as it can bore wash the cylinders.
2.) Don't let it idle at the same RPM and don't cruise at the same RPM or speed for more than a few seconds.
3.) Run a decent amount of boost. The more BMEP the better, for seating in the rings initially.
4.) Lots of engine braking is generally regarded as beneficial for break in as well.

Make sure to let your tuner know you're not afraid to run it at a nice optimal AFR initially. Let him know that you want to maximize burn efficiency in fueling, which means timing advance can be kept conservative.
