2001 GMC Sierra, Powerdyne Supercharger, and U7198

After talking with everyone there at Diablosport and contacting every local CMR Dealer trying to get the powerdyne tune for my truck I have decided to bolt it on and see if I can get it tuned in with my predator.
Diablosport would need me to do the hardware upgrade, then email the stock tune and wait for a custom tune. But I don't want to wait a month for the upgrade and then wait however long for the custom tune once it is returned.
The local CMR Tuner, Blow-By Racing, said that there is no template tune available from the Diablosport website for him to start with, and I think that was as far as he was going to go into it because I have not heard anything back nor had any returns to my messages.
So I have decided to try and see if I can get it streetable with my range of control. So far it is going very well. I have set both of my upper timing tables to the max of -20% and dropped the lower two degrees with a -8%. I have got my injector slope dialed in with another -2% (total of -7%) and have been dialing in the PE which is at -9% and seems to be right on. I will have to drive it a bit and see if the learning curve in my trucks computer will start adjusting it.
Once I have got my fueling set I can start bumping the timing back up and set it about 8% (or 2 degrees) below where it starts to knock.
I am suprised that my truck seems to respond to my tuning adjustments with the forced induction better than before when it was naturally aspirated.

So...you're local?

Why dont you shoot Johan an email....he can help.

Also, from those settings it appears to me that you are about 2 minutes from blowing that truck up!!
Please consider some dyno time or a real tune....
