not much power????? :(

Post by mxer97 »

i bought my 2011 silverado a month and a half ago, and sincei have put in a shift kit, cold air, headers, exhaust.... i purchasedthe diablosport predator to wake it up a little.... but it really has not done anything... is there anything to help wake it up? i figured for the 350 bucks it would come to life... next week im putting in the 4.10s

anyway.. with the 4.8's, really need to use good 91/93 octane gas, and the Diablo Tune, then do some data logging and adjust your fueling to get the fuel trims (ltft's) dialed in to notice a decent difference...

or, get a custom tune done for it...

With your mods custom is the only way to go. Do alot of logging first though. Its cheap for a good custom tune through monte.
