Dinan's Stage 1 Performance Engine Software for BMW 135 models provides a more modest increase in boost also providing substantial power gains. And as always, Dinan matches the new car warranty coverage for up to 4 years or 50,000 miles, including the possibility of consequential damages. No one offers better performance or backs it up with such comprehensive warranty coverage.

The Stage 1 Dinan Performance Engine Software safely increases turbo-boost pressure, along with properly retuned fuel mixtures, ignition timing and full map rescaling. The top speed governor is removed, enabling the 135 to achieve its full potential. The software also features remapped water pump speeds as boost increases, better controlling operating temperatures which have been notably excessive even at stock boost pressures.
