with the predator, #1 - they were all discontinued about 10 months ago now... and # 2, they do not have tcm/tranny support, so you would not be able to make any adjustments to the tcm/transmission, like shift quickness, shift pressure, shift points, torque managment, etc...
you'd definitely be better off getting the inTune... and yes I sell them and also offer a package deal with my custom tuning at a reduced rate so you'd save some $$.
http://intune.diablewtune.comyes the intune and predator will work for your truck... the preset canned tunes that come on them are general tunes meant to work across all trucks everywhere... the point of "not every truck is the same" comes into play when getting a custom tune done for your truck.. because no, not every vehicle is the same - which is why you'd get a custom tune done for it, so that data logs can be done and gone through, and the tune gets adjusted/tweaked specifically for how YOUR truck is running and what your truck likes as far as fueling, timing adjustments, torque, torque managment, etc etc... yes it's the same with the predator, with the intune, with the trinity... the tunes that come on them are only general basic tunes designed to give you some basic improvements/gains. BUT, the predator can not adjust anything with the tcm/transmission like the inTune or Trinity can.
