Hi,

i have a 2009 GMC Sierra Denali with Gibson Extreme dual Cat Back and Volant CAI. I was wondering if the trinity will provide me with more horsepower and lower MPG out of the box?

also what else it can provide me?

also which is better for me the trinity or the predator?

trinity is better... has more features, better data logging, and will have more functionality updates for it in the future, such as tcm/tranny support, and the ability to be able to tune more than one vehicle at a time...

the predator's will not be getting any more functionality updates, and are going to be phased out...

you want LOWER mpg??? hahaha...

ekekeke i meant HIGHER mpg

i would really like to know if someone tried it on the denali and what was the result?

with that volant CAI and exhaust on there, you'll need to do some data logging and get your fueling adjusted so that your fuel trims are in the 0 to -2/-3 range.. and then you'll notice some improved mpg, as well as even better throttle response and performance compared to the "out of the box" default tune settings...
