A little over 2weeks ago I loaded a different tune and all was well until my drive to work the next morning.. Within 10min of driving I started to give some throttle to see how well the tune would respond(this was while doing 65-70 stedy)and as the boost started climbing hard it stumbled, the gauges went fritz, the DIC said "service brake system" and I get a CEL. Well I didn't have my laptop with me but, I did have my OBDII reader/scaner and pluged it in and got "PCM voltage operation fault p061".. I cleared that and all was fine for another 10mi until I got into it a little and a few seconds after that the engine died with no CEL so I pull over turn the ignition on/off then now I have the same code again. I clear it, the truck starts and I'm on my way... This happend 2 more times on my way to work and 6-7 on my way home.. Any time I gave more than 30% throttle, 10psi or above 70mph..
As soon as I got home I put back in a file I knew worked.. I ran that tune for almost 2wks to make sure it was just the tune and everything was fine, until I loaded another tune that I had run for a couple weeks a few weeks before this problem that ran perfect until now..

I'll attach the files below>

The first is where the problem started, the second is the one I ran before the problem for 2wks just fine but, acts up now and the last is the tune I'm running now and the one I ran after the problem for 2weeks without any problems...

06' LLY, 6spd Alli w/TransGo JR., 4" MagnaFlow turbo-back system, PPE airbox mod, EFI-Live, EGT/Boost/Oil-Temp gauges.




Well I had the problem again!!.. After running a tune for a week with no problems I tried another one.. I took the tables for the Daily_trq_tun and copy/paste to my Hot_tun that works.. 5min down the road and as I start giving it some more throttle the CEL trips and service brake system in the DIC. This time it stayed running though... I hook up my OBDII scaner and get a PO606 PCM operation fault code... ARRGGGHH!!... So I hook up the V2 and load the tune file that works... Any help??.. Blacky, do you have any idea whats going on here??..
Thanx for any input.

Sorry I had to remove the tunes, we were told these were not for public consumption! Did you speak to the tuner these came from about the problem?

Cheers,
