Notice: Brew City Boost performance shop has permanently closed. This listing is preserved for reference only.
$349 – $599
Custom ECU tuning for 1999-2003 Saab 9-3 models with Trionic 7 engine management. Available via OBD-II flash or mail-in ECU service.
The Trionic 7 system used a Motorola MPC555 processor — a significant upgrade over the T5's 68332. This allowed us to modify more parameters including boost control strategy, individual cylinder timing correction, and knock sensitivity thresholds.
T7 tunes were the bread-and-butter of our Saab tuning business from 2010-2016, accounting for roughly 40% of all Saab tune sales.
