What is the difference between the Dos 70 and Dos 75?
The Dos 70 is optimized for higher altitude, while the Dos 75 is optimized for low altitude. The Dos 70 has a smaller exhaust turbine wheel to improve spool in the thinner air at high altitude. The Dos 75 has a larger exhaust turbine wheel to allow the turbo to flow more air at high rpm in the thicker air at low altitude. We recommend if your car lives below 4000ft of elevation the Dos 75 and if you live above 4000ft we recommend the Dos 70.
