Hello,
Received my new programmer today. 99 7.3 PSD. Do I need to disconnect tranny gauge when installing tune? Isspro gauges and tranny gauge is only one connected for power when key is in the "on" position. Any advice would be greatly appreciated.
Thanks

It should not pose a problem... the power draw from it is extremely small.

 

Thanks Ken. Tuned it to 60 hp setting and all I can say is WOW!!!!!

Its rare that a diesel owner doesn't like them!

 

My brother has always been a "gasser freak". I do believe after driveing my truck Saturday night that he is about to change.
