91 and 91 CAI tunes?

[dnar]

Hi, my Predator u7135 shipped with only 93 tunes.

Can someone please post up both 91 tunes for me please?

I am running 9r28.

Cheers.

dnar, just take-out (subtract) two degrees of timing in all three RPM ranges, that should be close to the same as a 91 octane tune. Where are you at and how good is the gas?

Thanks. I am already running 93 CAI with 2 degrees out across the range, but still suffer ST, mostly at part throttle.

My fuel is at +8%, +12%,+12%.

It must be the fuel. I put in the 93 cai tune and the only kr 1.5 at redline. and that is in Seattle using shell 92. But I have a cold air intake that sucks air from the wheel well. 2010 Challenger srt8

All motors are different. Thats why the ability to adjust the tunes is so important. With identical mods and identical gas, one could knock and another may not. One could run 12's and another 13's.
