When we build a turbo car or motorcycle, we like to include a Boost Gauge and an Air/Fuel (A/F) mixture gauge. The Boost Gauge is for testing and monitoring, but also it's cool to know what's going on with the turbo. Is there an air leak? Is the wastegate adjusted correctly? At which RPM does the turbo start making boost? Is boost constant or fluctuating? But it's also fun to watch. Under boost conditions like Open Road Racing, you want to monitor A/F for possible lean conditions. When you're riding around, A/F is constantly changing, but on the dyno or on the open road, you can watch it in a near-steady state. We like K&N's Air Fuel Monitor. There are others on the market, but we feel the K&N’s display is the best out there. Some gauges will drive you crazy at night with the LEDs flipping around the face of the gauge, or the display is hard to read, but K&N's display is not bothersome and is very informative and easy to read at a glance. However, the K&N A/F gauge is pricey at around $140 list. So, there needs to be some alternatives.

If you have a gauge on one side of the factory gauge pod, then it would look goofy to not have another matching gauge on the other side. We will be glad to provide a matching left/right set of gauge brackets that look nice and you can put whatever 2 1/16" gauge you want in there. Or we can provide just the vacuum/boost gauge and a matching oil pressure gauge. We like the Autometer 2 1/16" Z-Series gauges, they look and work great, have a black face and 270 degree sweep. They also sort of match the K&N A/F monitor. But if you don't want to use the K&N gauge, the set of Autometer Sport Compact Gauges (Boost #3301 and A/F #3375 {$60} or Oil #3321) have an aluminum bezel and more closely match the look of the factory gauges. So, you can mix/match however you like. Also, we like the Autometer Gauge cups which cover the bottom of the gauges for a cleaner look. These come in satin black steel or carbon fiber. Of course, we like the carbon fiber cups ($23 more each) better, but you can pick which one you want. There are some pictures below.

So, the "Optional Gauge Package" is more ala carte, these items are priced separately and you can mix and match if you want, and we can also sell you the O2 Sensor and wiring harness if needed. Our bike has the Boost Gauge on the left, K&N A/F Monitor on the right and Carbon Fiber cups, and it looks great. We always get a lot of compliments there. People spot the gauges first, then they see the Boost Gauge, and they say "Oh!". Then they lean over and look at the engine and find the turbo system, then they really start looking at the entire bike and pointing out details.
