Well back to the selling. I think the TB and plenum spacers are worth it. Most of these parts were on the car for less then 5000 miles, and come with all the hardware needed to install the parts. I put them all in so they come with good tech support hahaha.
Yes and no. You want one that can be adjusted by the user. The hyper crap is crap hence the name. SCT and the predators are really the only ones to use for the OBDII stangs. The predator can be adjusted by you or a tuner to change fuel maps and timming curves. Along with the cutom tune feature it has a tune from them on it ready to be installed. Be carefull when you buy a programmer used. They lock themselves to the VIN of the car and only one car!!!! People have been selling vin locked programmers online and it really ruins the community. I have no issues selling or buying online. Just do you research and use paypal!
Then you will need a tuner to change the speedometer and not set off Traction Control all the time. AND IT WILL DO IT!!!!! Some say it won't but I swaped from 3.55 too 3.73 and it would go off at anything over 50 MPH. I'll post those pics in here tommorow, I gotta go to bed. Later Matt P.S If you can't tell I am not out to screw you. I really just want my friend to hurry up with his 100 shot. So I figured I would try and help sell his parts.
