    I can tell with my exhaust, I just ignore it.

    You heard wrong. The engineers that designed the system to get MPGs.

    the 8>4 switch drove me nuts when i got my exhaust done, set my tuner to run in v8 mode all the time. in certain situations i the mpg is just as good or better then having the afm on, but i would say that it did better with it on. my average went from 15.5 to 14.8 or so. not that much of drop.

    you can NOT adjust any tcm/tranny settings with a predator... you can not change anything like shift pressure, shift points, tranny torque management, etc etc... predator's never had tcm/tranny support for 2007+ vehicles...

    plus, all predators are dead and gone - they were all discontinued about 1.5 years ago now...

    for tcm/tranny support, plus newer updated tune files, easier data logging, more parameters available for custom tuning, etc etc - you would need to get a diablosport inTune or Trinity...

    you won't be able to do anything for the tranny, etc with the predator....

    so yeah, just an fyi...

    uhhhh, not really....

    myself, as well as several hundreds/thousands of others, get better mileage with it disabled/off... the DOD/AFM only helps you if you do a LOT of highway driving, all the time... I gained 2 mpg just by disabling the DOD, and so have many many many others...

    if you do more town/city driving than highway driving, then it doesn't help and it actually hurts... plus there's the whole oil burning issue that it causes every time it switches between 4/8 cyl. modes, which was even confirmed by GM in a technical service bulletin...

    so no, DOD/AFM does NOT always help you... plus disabling it helps to improve throttle response....

    Like i said...i pretty much JUST want to delete AFM...tranny shift points i really dont care about...if i wanna do that down the road ill sell this one a get a trinity or something...for 110 bucks plus free shipping for a NEW in box one just to delete AFM...cant complain to much...My thought is if your truck is a V8,you might as well use all 8...just like my last trucks

    This is what the site said about my tuner...

    The predator is a state of the art, high performance tuning flash programmer in a sleek handheld design. Once connected to the vehicle, the predators internal computer recognizes the vehicles PCM and automatically picks the proper tuning files designed specifically for that PCM. Inside the predator's memory are the actual tuning files that optimize spark timing and air/fuel ratio curves. The transmission parameters are remapped to improve the shift characteristics such as shift firmness and shift points. Unlike other 'tuners', DiabloSport's programming is performed in very small increments throughout the entire RPM range, for a smoother, wider and a more predictable power delivery. DiabloSport engineers spend many hours on the dyno, street and track to ensure the tunes provided with the predator are the best they can be.

    the site lied... they probably just copied that from a different model predator's description and use it for all of their predator descriptions heh...

    there is no tcm/tranny support at all with the U7194 model predator....

    as for other things they say about it that are wrong:

    yes you can adjust the tire size and gear ratio to correct/calibrate the speedometer...

    it does not log for 30 minutes... it will record a log for 3-5 minutes....

    it has an 87 octane tune, and a Diablo Tune - the diablo tune is made for 91 octane gas...

    and hp/tq increases are not up to 30, heh...

    on 87 octane with 87 tune, you'll gain about 13-16 hp/tq

    on 91+ octane and diablo tune, you'll gain about 20 hp/tq...

    If you are doing a lot of non-highway driving, the engine should rarely go into V4.

    I am going to do an experiment, I am going to use my Hypertech to disable AFM and see if I get better MPGs. I currently get ~18 in city/highway combo driving. I will give it a week.

    Great price on the Predator (relatively speaking). I know that the newer tuners are out there but my older Predator works just fine, especially after Lew custom tuned it. Nice score, you'll be happy with it.
