have a ? for u guys .... I have an 07.5 thats the new body 5.3lL suburban vin code Z ... had the preditor for about 1.5-2 yrs. ... all i am using is the 91 octane tune and i have been experiencing spark knock going up hill or @ WOT and sometimes while passing .... wont even powerbrake with stabilitrac and traction disabled ....... please HELP .....U7194

What revision?

the tranny nannies on the NBS rigs won't let you do a brake stand.
as far a KR, have you dialed you part throttle fueling in? Uphill and WOT are the two times you are most likely to see KR

like that the "tranny nannies" part throttle fueling? is there something i am missing thought it was just plug and go but according to u guys and i admire your vast knowlage of this field, there is alot more to it .... i'm sure if someone explained it i could do it juse fine

tranny nannies are there, from GM, to protect the transmission for harm. that's why no brake stands, mussy shifts, and slow starts off the line.

you can install a tune and go, if you want. you can also follow that link from Monte and get MORE out of the tune. the canned tunes are the same for everyone, but no two motors are alike, so Diablo has the capability to compensate for those differences and get the most out of your motor. Most HP, Most MPG.

would the fact that my motor vin code is a Z have anything to do with it. It is a flex fuel capable motor i have noticed that when i use ethanol i have a significant hp increase and NO spark knock and as with all E85 motors Crappy MPG with it

mike or joseph any updates!!! I'm waiting for the original tune to be added so I can use the predator on my 09 avalanche. I sent you both an email yesterday with my info

Anybody else sitting here thinking like "I wonder when they'll get to revision Z?" Lol

How about 9t09tcm???

Wow, my predator is fubar... can't run diagnostics or do anything with the tune. Might need you guys to walk me through a forced restore so I can re-update the predator and hope it stops this nonsense... if not, what's the warranty on this thing?

Edit: Yepper, I'll be calling in monday unless yall have figured out what the error is... I tried to restore my original backup and it still acts like it can't talk to the vehicle at all. Keeps saying to make sure the ignition is on, even though it is.
