I have a 335i w/ a AT. I have looked at the various piggy-back ECU software and would like to get some feedback from users. I am looking for an Emission compliant tune that will not cause me any issues each year I have to be tested. I am not interested in doing the pay under the table deal. I am not looking for the most power but the easiest and most reasonable software that is 49 state legal. I appreciate any and all input. Thanks
