Pyro guage problems??

[Sonic_Superduty]

Im currently running a 1800* pyro from isspro I love the guages, but last night I noticed the pyro needle wondering around all over the guage....ex: when Its at idle and warm it normally reads 290-300 range last night it read 6-800 and it was just idling in the drive way...... have any of you out there had any problems like this??? could it just be a short some where or is the guage more than likely shot???:thankyou2:

I had the same problem with my fuel pressure gauge, it ended up being the sending unit, maybe you should contact Michael on this site and see if he can help you out, he works for ISSPRO http://competitiondiesel.com/forums/member.php?u=191
