I figured i would give some feed back on the programmer.
I set it on the tow tune first and drove it for a couple of days and
I felt a noticable difference but nothing to get worked up over so
today I figured I would try the performance tune and I drove it
around town and it didn't impress me as much as the tow tune
just my .02 cents.

 

When I had mine the first time, my truck also seemed to have liked the 87 more than the 91

 

i finally ran all the 89 octane out of my truck and put some premium in so i could try the tow and performance tunes, and the dam thing wouldnt work!? i plugged it into the computer and it says its in "boot mode" and thats it. hopefully i can get this straightened out... im gettin pissed...

 

yea i would be too... to much anticipation for fora let down. reminds me of high school when you used to get them girls that would get you all geared up for a hot date n after dinner n movie and w3hatever else trick you had she tells you she is on the rag

 

and this one time.......................at band camp.........................

 

Hence the term "Red Wings" and it don't mean hockey!
