Stage I+ ECU Upgrade
Stage I+ software, along with larger fuel injectors, provides even more horsepower and torque, raising the output to 235 and 275, respectively.

For optimal results, our cat-back exhaust system is highly recommended with the use of the Stage I+ system. This ECU upgrade (Stage 1+) requires an injector upgrade.
