I decided to change my analog Speedhut boost and wideband gauges with their digital gauges. I called and asked if the change would be a plug and play swap and they said yes. I received my gauges and the boost gauge was plug and play. I went to hook up the wideband gauge and the plugs were completely different. I called Speedhut back and they said "oops, you need the AEM wideband controller for that gauge". I said fine, when can you send me one. They said, "we don't stock it, you need to buy it directly from AEM". AEM won't have in stock until sometime in March.
