This is my first post since joining in April. Have been lurking T. D. R. for about a year and sure have learned alot. What a great source of information. Anyway, got the Power Pup & Outlook Monitor. Couldn't wait to try it. Loaded the performance program and went for a spin. The advertised 90 HP from this program should have given my truck an additional 30%. But to be honest with you I didn't really notice much of a gain. Didn't have time to try the extreme program last night so reloaded the stock program. A few months ago i had the dealer flash my truck with TSB #18-004-04 (poor cab heat) which allows you to control the idle using the cruise control buttons. This morning I went out to warm up my truck before work and found that the TSB flash has been erased by the Power Pup. Maybe this is an isolated incident, but I kind of doubt it. I am concerned for you folks with the 600's that have had the flash for poor fuel mileage. How will you know if it's gone or not? Guess I have to face the music and go back to the dealer and have it reloaded. :{my sig. didnt show up my truck is an 04 305 555 Im returning the power pup tonight.
