Installed my new 2805 on my diesel. Has a lot of power but is vary slow off the line( a 2 second hesistation). the bigger problem is I had it in Performance mode, was driving over an hour then lost all power. engine stayed running but no accerlation. (pushed the pedal down and wouldn't budge). Put program back to stock...ran like new. Please tell me what is going on..... other potential buyers want to know before they purchase.
