So last fall I finished my 2860 install and got fully tuned on 93 and E30. I'm happy with the cars performance and am ready for spring to get here so I can bring it back out and maybe put it on a Dyno. Now that I really don't have anything left to do to the car I've just been wondering if anyone has gone big turbo with one tuner, gotten tuned and then tried another tuner just out of curiosity.
