Unlike some other "programmers", when you return to stock with the DiabloSport Predator, it leaves no ghost images or gaps in the data stream where the re-writes were done.
And the Predator is sooo much more flexible with tuning options than the competition. I delved into programmers very deeply before I bought the Predator and I gotta say it was the best bang for the buck performance mod I've ever done to my 300C SRT8.
The Predator is easy to use. As with all programmers, the first rule is RTFM... Read The ****ing Manual!!!
If you decide to get the Predator, PM me your email address and I'll send you some helpful write ups on using one.
I get nothing for this. I am not affiliated with DiabloSport. I am just a very happy Predator user.
