Diablosport Predator questions
I am thinking of picking one up here shortly. How are are they to tune with, what gains will I see, and does anyone have any information on how to tune with one?

If your not ready for Edit or HPtuners, it's a great product. I can't complain about mine. Most cars can pick up anywhere from 10-20hp at the wheels. Local GTO picked up like 17 RWHP while tuning with it on the dyno. Diablo also has great customer service, I accidetally ripped the cord out of mine (dropped it and caught it by the cord) and they replaced it free of charge, it was over a year and half old. If you need a custom tune Johan at Diablo will usaully get you what you need with in 24 hours.

It's what I used to tune my car after the header install.I went from 322 after the headers were installed, to 348 after tuning with diablosport hand held unit. You can also troubleshoot the car with the unit and delete codes as well, not a bad tool. if you are planning on going heads, cam, or FI, I'd go with an ls1edit or something of that nature. I think that the diablosport is only good for so many variables. Overall, I am happy with mine, and have no complaints.

Here is the thing. I would love to pull like 10 to 20 hp more out of my ls1, that would be great. I am getting headers here shortly so that will help with that tuning issue too. BUT...I dont have access to a dyno, and couldnt tell you the first thing about tuning. Except where to plug it in. Basically is it hard to learn, and can I really screw something up royally if I dont know what I am doing? is there a way to revert back to stock like an hpp3?
If I buy a used one is there anything I need to look for? Are they vin specific or multi-car-functional?

It's realatively easy to use, and the factory program does get saved in the unit, and can be resored at any time. After a header install, you will be running rich, so you will have to lean it out some, there's only so much that you can do percentage wise, so unless you set the rev limiter way too high or something like that, I don't think that you could srcew anything up too bad. I think I went 1% from full lean, and actually pulled 3% of the timing out, on the dyno it made more power that way. Best way is with a dyno to test the settings, but if you don't have one available, use the butt-o-meter, try a few things, see what feels the best.

They are vin specific. I think it's 75 bucks to get it reset from diablo, however, if the factory tune is still stored in the unit, they will not reset it. they will only reset the vin # on units that have gone back to stock, if they didn't do it, one guy could buy a unit, and for 75 bucks a pop, tune all his friends cars with the same unit. Good marketing really.
