pontiac G8 Gt Speed

Post by lightguypro »

hello, new to forum and the Diablosport, picked up a used predator, U7194, I dont know much about tunes, but just figured plug and play, forgive my ignorance, but this seem so easy to do. put the diablo tune into the 2008 G8 gt, and woke it up, great stuff, . at this time its all stock other then gibson axle backs, mid muffler delete and have an xpipe in its place, had a generic cold air intake, but took it off, due to safemode when WOT, guess it dont like too much air.
I am in So-Cal, wondring if you have anything in the area, to get it tune right?
also, are you still supporting the Predator U7194, I still top out at 137mph, cant seem to take the speed limiter off, I noticed other topics where people posted the file, but seem so old, not sure if its being supported, is that something I can do?

I've already been replying back and forth with you via email all yesterday afternoon...

You can't get anything fixed/tuned at this point anyway, since you don't have a pc interface kit for it, so no way to do anything for it... you can't update the tool, can't get custom tuning done, etc...

yes you can.. need a usb/serial cable.. and a 12v, 1amp power supply, with the center of the tip positive.. take the predator with you so you can make sure the tip fits it...

and yes I can do a custom tune for you no problem..

Hello so I had a question about this device. I have 08 g8 and it has a btr stage 2 cam w/ a stock converter, will I have to get a custom tune? Or will the device already have a setting for that?

That would require a custom tune... There's a search area where you can search for custom tuners ...

That cam is not something I would do myself via an email tune...
