R-Spec Performance Ltd is the sole distributor for Gizzmo Electronics in the UK. The new Gizzmo V4+ (OLED White Display) represents a very finely polished revision of the previous V4 whilst adding some excellent new features. The V4+ now displays vacuum in inHG, cmHG or KPA, has smoother screen transitions, improved icons, better solenoid control and a ton of other very subtle improvements with the most valuable being antigain. Whereas gain effects how aggressively boost rolls on, antigain effects how aggressively the V4+ decreases the duty cycle in the event that the vehicle goes over the boost set point.
