Do you have a Evo X on cobb?
This is the tune you need in order to run an aftermarket intake on your EVO X safely.
A wideband IS required in order to purchase an Etune.
Supports up to 3.5-inch intake, Stock Downpipe, 3 port EBCS or Stock.
This ALSO supports SST tuning. If you have an SST Dual-clutch trans this is a must as off the shelf mapping does not provide any increase in clutch pressure. Extend clutch life, and much more firm shifts.
