- TurboPerformance Charge- & Boostpipe
- PureTurbos Inlet pipe
- Ecu custom tune (435hp/640nm) with Shell 100 octane

During winter months I'll install the TTE550 with the B58 pump and see what happens. Otherwise I'll upgrade to XDI or the Supra pump.
Europe has the best octane, but 500 crank hp, or 450whp (Dynojet) requires 19~20psi (uncapped), which is more than RON100 can handle, unless it’s freezing cold all the time.

Not many tuners want (or have the skill) to work around octane. Race gas, WMI or ethanol would make things a little easier.
