All stock had been sold already. Apexera has now resumed making the mechanical boost meter (white face with EL backlit and red LED lighting). Price has now been revised upwards to $180. Will update first post of this thread tomorrow.

Any updates on whether apexi is making water temp and exh temp gauges, without use of the controllers?

Will send an email to find out.

I think the EL series has already been permanently discontinued, except for some stock left over of the ELII mechanical boost meters.
