Predator Help
Ok I had the car to the dyno. The first pull in red was with the predator tune installed. Then the next tune was with the stock. The guy said that I needed to richen it up more but seconded pull (blue) was way better and leaner. Anybody have some suggestions????

Re: Predator Help (DCBStingray)
no pic. however, i will say, i wouldn't recommend flipping the tune back and forth as it does take a few miles on the car with any tune for the computer to relearn. also depending on mods you may need a custom tune. factory is very non specific. what works for one car won't necessarily work on the next.

:iagree:
What are your mods? I have an MN6 with bolt-ons and the standard Diablosport tune on the car was unimpressive, in fact, I was running rich to begin with and the standard Diablosport tune fattened the fuel up even more. I contacted James, sent in the data from the PCM along with a list of my mods & what the motor was currently doing. The CUSTOM Diablosport program made a BIG difference. :thumbs: I haven't gone to a dyno yet, but the SOTP was definitely noticeable over the standard Diablosport tune, and NO CODES. You may need a custom program. Get your Predator dealer to hook you up!

Re: Predator Help (DCBStingray)
I have LT headers a 02 LS6 cam, ported and poslish MAF.
Do you have offroad pipes with no cats, curious?
Any specific reason you ported your MAF? That's not always a good idea, and the factory MAF meter is actually good enough to flow well enough for most modifications. This could possibly be lending to some of the extreme leaness in the lower rpms, aside from the Long Tubes. If anything, I would suggest getting the larger meter from the Z06 that is calibrated with your factory electronics.

Re: Predator Help (DCBStingray)
Who did you purchase the unit from? I would attempt to go through them for a custom tune. If they are unable to do such for you, I can help you, but of course I'd have to charge a 1 time fee to transfer your support over, but it is reasonable.
As for putting the screen back in, well, that's not really going to do much to help you, IMHO. You've already disrupted the way the sensor sees the airflow. The factory MAF flows well enough as is.
