Is this tuner worth the money? My car is pretty much stock other than a Blackwing and some cold air screens. I may change the air duct, but that's about it for now until I eventually do the exhaust. I need a quick fix for the track to get into the 12's. I ran consistent 13.0's yesterday. Best being 13.060@106.98mph. I don't want any custom tuning or dyno tuning right now. Will the Predator get me at least a 12.9 by removing the torque management and firming the shifts?? Is there anything else I'll need to adjust??
Also, if I decide to get a pro tune down the road, will I be able to? Do I have to change everything back to stock first? Thanks for the help!
form what it sounds like u probaly do need an tune (ie engine management upgrade to make up for the upgrades) if u did all the from stock with no tune you engine still thinks its stock and is not making adjustments for the upgrades, thus no HP or even is some cases an little HP loss
take for instance
if u change all or an few of the fallowing you will need an tune and an dyno run wouldn't hurt to
Intake, "Air box/filter thing", exhaust manifold, fuel injectors, intake manifold (if different from OEM one), Camshaft, rear axel ratio.
the predator might help with the shifts, not shure on doing the tuning required to ajust for anything else
Mine made a nice noticeable driving difference. Do you have an auto or manual? If you are just trying to get 0.1 second I have to believe it would do it just based on how much quicker the car feels but would be better to have someone with track experience tell you that.
They recommend taking the Predator tune off for every time it goes in the shop for service. With the new Predators you can put your stock tune back in and then the unit could be changed to another car; like if you got a dyno tune later still get something for selling the tuner. The older ones would not change between cars.

Thank you for the replies. Minitech my car is an Auto with 3.15's. Could you tell me what you changed on your car? Shift points? fans? Did you remove torque management? Does the unit basically do everything at the push of a button? Or do you adjust each thing yourself? I ordered one earlier tonight and it should be here before the end of the week. At which time, I will use it and then go to the track over the weekend. I will be able to get some "real" results that I will post so that we can see if it is a worthy mod.

It woke my stick car up. I also have changed the fan settings. Since mine is an older revision I will be able to tune out the O2 sensors after I install long tubes.
A couple of misconceptions, first being the older units as long as the revision isn't 1.0x can be swapped car to car after restoring the factory tune. That "unlocks" the tuner which can then be moved car to car. Then there was a comment that a tune was needed after a CAI or other minor changes. These cars learn new settings after minor changes. They may run rough but a 20 to 30 mile drive will relearn the settings.
Back to the original question, I'd think you would be able run high 12's after the Predator tune. Once you gain some knowledge you can log data and then adjust your fuel trims for added benefit.
If you buy the claims of Vararam you'd pick up the time your looking for. Just a thought.

Reason: Corrected a revision mistake
From what I have read on the Diablo site, the Diablo Predator 7198/revision 1xxx, becomes forever locked to the original vehicle it was purchased for, even if the original tune is returned to this vehicle. The model 7198/ revision 2xxx and higher, can be used on other vehicles if original tune is returned to first vehicle it was used on. I'm pretty sure that this info is correct.

Thanks again for the help! I know the Vararam works because I've seen it work on another C5. (The car gained a couple of tenths.) But I chose not to go that route because I wanted a simple install and as I said, I have/like the cold air screens. I'm going to try a larger cold air duct and the Predator for next weekend. I'll also clean the filter up and adjust tire pressure. I figure these are some easy mods to work with for now.
What did you guys raise your shift points to on the auto? How about the fan settings? (thanks again)
For what the Predator is it does a good job. It woke my AUTO up and I was able to tune my long term fuel trims pretty easily. When I upgraded to bigger wheels it was a 5 minute update to the tune to get my speedo right again. When I do the headers/gears upgrade in the next year or two I will go back to stock and get a dyno tune. There are plenty of places that you can get it for close to $300 as opposed to $400 as most of the big places advertise it for.
I have a 99 a4 convertible all stock but 3.73 gears and I really like what the Predator did for me. Mine is a weekend driver and no racing. Changing the shift times and removing the TM just made it a lot more fun to drive. I didn't need the more extensive/expensive capability for my application. Also Diablo has a great forum with quick reply's and valuable information. The logging features for adjusting LTFT's are very easy to use if you have a laptop but not as good with just the unit. If you buy one be sure and get the data cable to go with it.
My car came with a predator and the tune installed. I restored the factory tune and drove it for a while and then put the Predator tune back on. I definitely noticed a difference. I like the predator tune. Since then, I made some other mods and ended up getting a dyno tune (first I removed the Predator tune so the device could be used on someone else's car). I think the Predator is a nice tuner and gives you quite a few options: It comes with tunes from the Company and it allows you to change individual parameters as well. I still have mine if someone is considering one but doesn't want to pay new. You can PM me.
In any case, I think the OP will be happy with what he is able to do. Let us know!

You are correct, revision 1.03 was the release revision and it won't unlock, but most were updated to the 2.xx revisions. I know the Revisions 2.10 to 2.13 will unlock and move around easily. The newest 9r0x revision will unlock and move. Without doing any research I'd guess you could send in a 1.xx revision and get the 9r.xx for $99. plus the unlock charge. I don't know.
Mine is a 2.13 revision and while it would be nice to log data via a laptop, if I send it in for the update I lose the ability to play with the emission systems settings, so I'm staying with my revision.
I actually would prefer the 213 revision, because it allows you to turn off the rear o2 sensors if you remove cats or install headers, something the newer ones will not do.

i really like mine. IMO it works best with a auto (mine is an '01 z51 auto with 3.15). I did the vararam and corsa first and after my computer adjusted to these mods I noticed a slight ping at WOT. So i replaced the plugs and added GM performance wires with no change (but now I could see the condition of the plugs - which looked fine - which mad me fell better) so I added the predator and it took care of the slight ping plus it felt even stronger. After some extensive research I did tweak my tune some. Here is one link that I found useful on tweaking.
