Major problems with UltraGuage

[Pryme]

Been using ultragauge for more than 3 years now on my mirage, haven't had any problems whatosever. One thing I observed though when I turn up the refresh rate it seems that the engine would run sluggish, return it to default and engine power returns.

Sounds like a major problem to me.

I don't think so. The engine is running fine going 4 years now. No check engine light whatsoever and the ultragauge is still plugged in.
