The digital units are nice, recording peak values etc. , but I'm still partial to analog. At a quick glance you can easily tell if something is out-of-wack.
I've had the combo boost/egt and transmission temp from Westach on mine for the past year and like 'um. I'm about to add their fuel pressure guage, that has a user set warning high output LED. When that LED goes on you can also run a buzzer or with a relay anything else you want, i. e. a second fuel pump. Westach also offers switches for multiple senders including thermocouples.
I dunno, but for less than half the cost of the SPAs I feel I'm well enough informed, and they complement my stock cluster.
my 2. 5 cents
