Im looking for oil pressure , fuel pressure and water temp gauge. Is it important to get gauges that can record and have play back record feautres? Dont know if its that important to monitor it at WOT... or at cruising speed I can just look at guages and see if everything is fine by its normal operation temps?

 

If you have the spare money go for it, but to me they are more for looks as when stuff really goes bad I doubt you will be watching a gauge and able to react fast enough even if you do see it.

 

for instance if my oil pump is acting weird or about to die...I want to be able to instantly see whats wrong with it at idle or cruising speeds

of course at WOT if it goes it goes
