2009 Challenger RT 6 speed - Diablo tunes yield no gain

Post by toofart »

I just got the Trinity, and I updated to the latest crom. I bench tested the 91+CAI tune and the 93+CAI tune. With 94 octane fuel in my car, both tunes yield absolutely no measurable gain. Actually, the 93+CAI tune is slightly slower.

I do have a Mopar CAI. I datalog during my tests, and I don't see any different KNK ST events on either pulls (stock, and diablo tunes).

As you may know, the '09 5.7 Hemi in the 6 speed is the only 5.7 to require 91 octane from Chrysler. So my question: are the Diablo tunes optimized for the 6 speed R/T or not?

We gained roughly 10-15 hp on the 6spd RT's we had in the shop.
Why would you expect to see any different ST KNK between the tunes?
