ATT-TEC Tuning vs the BMW 1 Series M Coupe

It’s an epic battle and the result is perhaps even more impressive since there are two winners. Nobody loses out here, and if we factor in the by-standing customers, three categories of people are winning here.

ATT-TEC simply took on the 1 Series M Coupe and improved the bits that customers weren’t too happy about or areas where they wanted something extra.

The power was obviously at the top of the second list. The twin-turbocharged 3.0 liter straight six cylinder engine now has two stages of tune.

First, there’s a simple ECU upgrade which spools the engine up to 400 horsepower. The second package is a little more advanced but it does take the grunt up to 460 horses so it’s easy to justify.

The second package does include a larger intercooler, the fitting of a custom Akrapovic exhaust system and an even more aggressive remap of the ECU.

In terms of suspension, the BMW 1 Series M Coupe does excellent on a track and almost reasonable on a road. In hoping to make things better on both levels, ATT-TEC chose to fit a new setup altogether.

Obviously, the best aftermarket option so far is the KW adjustable coilover package which serves up more favorable ride options.

Out at the end of the day, ATT-TEC rounds up the entire package with a new set of 20 inch ADV1 5.0 TF wheels and some Michelin Pilot Super Sport tires.

You can nitpick, but it’s hard to find people who’ll believe the flaws you’ve found even with this sort of package.
