I'm looking at a tune for my 2013 328i and I was looking around at some different Tuner companies such as BMS, Active Autowerke, and Dinan. I don't currently have $700+ to spend so an Active Autowerke and Stage 1 Dinan tuner are out of the question. However, I did notice a tune by Dinan, the DINANTRONICS Sport Performance Tuner , and I was wondering if anyone could give me any insight on this particular tuner. I would also like some insight on the BMS Stage 1 tuner as well, they're both in the price range I'm looking at staying in. I currently run 93 octane in my car with no upgrades yet done to the car, I've had the car for a week now... Any info on reliability, any damage or problems they could or are known for causing would be great. I want the tune that will give me the biggest bang for my buck as long as it doesn't mess up my car and I can take it out so BMW never knows I had a tune in the first place (the car is still under warranty and I'd like to keep it that way). This is my daily driver so I CAN'T afford to break it...
