Boost Controllers Autopassion's range of boost controllers ranges from the simple GFB gated Atomic bleed valves to the full digital electronic units from Blitz and Greddy.

The GFB Atomic boost controller is a simple and affordable way to increase your boost level. These controllers are engine bay adjustable and are fitted in-line of the wastegate actuator.

If you require something with easier in-cabin adjustment, then the Turbosmart single and two-stage boost controllers are more appropriate. The single-stage two way adjustable is ideal for cars with an internal wastegate, where low boost is set at factory level and high boost is whatever you require. The Turbosmart two stage adjustable boost controller is ideal for cars with an external wastegate, where boost level on high and low can be set exactly to your requirements.

Turbosmart also make a digital electronic boost controller: the e-Boost. It utilises a 16-bit memory CPU, which enables the e-Boost to respond quickly to your boost demands. The e-Boost has boost/vacuum readout (in psi, kpa and bar). A different boost setting for each gear if required. Auxiliary output for a boost light, water spray or water/methanol injection. Programmable alarm facility for full boost or overboost. The e-Boost is easy to mount in a 2 5/8 inch (66mm) cup or in a pillar mount system. The Turbosmart e-Boost can be used with any turbocharged car.

Blitz boost controllers are also available from Autopassion. Blitz offers a range of electronic boost controllers for single and twin turbo Japanese cars. Their range starts with the Dual SBC Spec S, which is a full electronic boost controller with boost gauge, volume control, four separate boost settings, warning overboost facility and peak boost hold. Blitz also makes a Spec R version that is suitable for cars with a twin turbo set-up. If you prefer to use the ultimate in Japanese electronic boost control devices, then Blitz caters for that in the sequential SBC DC and SBC iD II electronic boost controllers. The DC and iDII are a no-nonsense boost control system in ½ DIN size. They offer everything the Dual SBC has and adds; scramble mode, data logging, graphic display, voltmeter and temp gauge.
