is my tune safe?

[SVTdubs]

mods are 4lb lower, JLT intake, FTVB, diablo chip and tr6 plugs

I see about 11psi up here in colorado and my maf is fine (I have a mafextender in the truck just incase).

the max timing is set at 18 degrees and here is the a/f in my tune...
do you think its safe?

LoL yeah that is pretty rich! IMO, 18 degrees is pushing it for 93 octane.. especially in cold air. We run 17* in the summer and 15* when the temps start dropping.

Definitely rich!

91 octane is all we have up here but I only see 11psi and the truck only makes 377rwhp (304 uncorrected).

I wonder if the elevation allows you run more timing with less octane? I am no tuner, but I would not run 18* on 91 octane around here... no way. But then again we see 13-14#s with the 6lb lower.

The lightning motors CANNOT take the abuse the cobras can.

the tuner tunes all of the L's in the area and has 97000 miles on his personal truck which he races every week and runs 13.3 up here with a ported blower, 6lb lower, chip, stock maf, stock fuel, 12.0 a/f and 21 degrees on 91 octane... no winter tune... I dont know what it is either but they have NEVER had a hurt motor and Ive talked to numerous customers of theirs.

they even have a customer who runs a 6lb lower, 2.8 upper and 100 shot on a BONE STOCK motor... it runs 11.4 UP HERE!

I trust them, I may go back to them and get the flip switch put in and get a second tune with 12-14 degrees for if I ever go back to chicago. I have the mafia sitting next to the CD changer if need be as well. I love my a/f guage, I wish I had one in the cobra so I would have known something was up....

I guess its the corrected vs uncorrected numbers is why the trucks last up here. In chicago a 400rwhp SAE truck makes 398 or so UNcorrected... here it makes 310 or so.... maybe thats why we can run more timing because its not making the same kind of actual power.... I have no clue but thats my theory at least...

Dude, I didn't change my tune AT ALL when I moved up there. The elevation combined with the lower octane basically neutralizes everything.

I'd say your tune is PLENTY safe.

its my understanding that the 02 sensors work way harder up here and the cars run really rich.... who knows though

WTF, O2 sensors turned off right? Fugg it!
