IE ECU Performance Engine Tune For B9 Audi A4/A5/Q5 2.0T

Audi’s factory calibration for the B9 A4 and A5 2.0T constrains a platform with significantly more capability than it delivers from the factory. The iE POWERlink Tuning Suite removes those constraints through a complete ECU recalibration designed specifically for the B9 platform, delivering substantial increases in power and torque with the polished, real-world-validated character that defines iE’s calibration work. 

NO CORPORATE FILTER

This iE tune safely reprograms the engine computer, stripping away those limits and replacing them with a new, unchained personality. Experience savage acceleration and custom-coded performance tech that makes your A4 & A5 unhinged when you want it, and civil when you don’t.

Advanced safety logic and AutoProtect intelligent programming continuously monitor each cylinder and pull power instantly if something isn’t right. You get massive power and torque from a tune that dials it back when you need it most.
