I purchased a Diablo Predator Hand Held Tuner about 3 months ago. Since then I added exhaust system and filters. Is it true that when any mod is added I have to go back and retune? And when I did load the predator in my C6, i just did the performance upgrade. Im really not sure what else to do with the tuner? Tweaking for example
I sure hope someone answsers your question, Tommy. I'm interested in a Predator, but I'm not sure what performance gain I would get after shelling out $390 bucks. Did you see a gain after the performance tune (whatever that is)?
The Predator has a diagnostic funtion that allows you to monitor certain readings. There are a bunch of old posts in the C6 Scan & Tune section about this as well as altering the Predator tune. You can access this section by clicking on forums, select main to go to the main section listings and go to the C6 Scan & Tune section. Use the search feature to dig up the old posts.
Your car probably will be running ok using the Predator stock tune with only intake and exhaust. Since every car is different it is a good idea to use this diagnostic feature and alter the tune to get the most out of it. Granted this may not be as good as getting a custom dyno tune but it's still can be very helpful.
