I had a dinan stage 2 tune on my n54 e92 335i and never had a problem.

The stage two is like $2g's so a bit pricey, but they will match your warranty and BMW will acknowledge this tune and will still service your car hassle free.... Just saying.
This is NOT true. BMW and Dinan have fallen out of bed so to speak over the years and all BMW dealerships won't just overlook a Dinan tune if you have one. Even my dealership 3-4 years ago warned me about this, and so did the Dinan installer. Dinan and BMW are now competitors with their new performance product line, and BMW has zero incentive to place nice with Dinan.

Dinan's stage 3 tune on the N55 motor for the E90 model cars required $3000 in additional upgrades before labor/tax including an upgraded intercooler and oil cooler. Now you're looking at having to spend probably an extra $4000 on supporting mods, plus they charge an extra $500 on the stage 3 tune. $4500 for an extra 18hp? No thanks. Only if I was tracking the car would I spend the money on the oil cooler and intercooler (but not theirs anyway).
