Description
Why the M270 M274 Responds So Well
These direct-injected 2.0T “250” engines have strong headroom in airflow and torque modeling. We correct the torque tables, boost targets, and λ/ignition blends, then shape torque in lower gears for reliability.
- Stage 1 (stock hardware, 91–93): ~+50–65 whp / +70–100 wtq
- Stage 2 (downpipe + better intercooler): ~+70–90 whp / +100–130 wtq
- Options: high-altitude maps, hot-climate IAT trims, E30 blend files (by request)
Fitment (examples)
C250 / E250 / CLA250 / GLA250 / GLC250 and other 2.0T “250” models using the M270/M274. Unsure if yours is M271 vs M274? Send VIN and we’ll confirm.
