We have found HUGE performance gains on these new GSX8s!

As we continue to perform our custom ECU flashing R&D for each intake/exhaust modification, we inevitably come across setups that perform better than the rest. This particular intake/exhaust combination is one of those setups! If you'd like our custom intake/exhaust-specific ECU mapping flashed into your ECU, purchase our Mail In ECU Flashing Service at 2WDW.com. If you have any questions about performance modifications or tuning for this platform, don't hesitate to email us at [email protected]. We are always happy to help!
