Is there such a thing? Looking for one with 3 probes to monitor all cyl and something with a warning light. Cheapest I find is around $450 (redlinegauges.com), anybody else come up with something less expensive to help montor the engine? I really don't need to see the temp, just a light that blinks or something when I get to a preset temp limit (ie bad gas, etc) after its been tuned. I only spent $550 on the pipes and it kills me to spend that much for gauges! ha ha Thanks!
