[NESW20]

for what it's worth, i took my MR2 to a nationally known (in the MR2 community) shop to have them install and tune an AEM EMS on my car. i'm a high compression stroker, so it is difficult to tune, but i figured they would do a good job because they specialize in that car and engine.

they didn't do a good job. my engine still runs, but there has been internal damage done. i have replaced all the crank bearings (dropped the pan and rolled them in). i have since retuned it myself on a local dyno and on the street, and it runs WAY better than it did when it left their shop. it will need a full rebuild later, but for now it runs well enough.

that being said, there are still certain people/shops that i would feel comfortable letting them tune my car. i would just be a lot more attentive and not hesitate AT ALL to make them stop if i didn't like something they were doing.
