2014 chevy silverado i3 tuner

[Willstefane]

I have a 2014 chevy silverado 6 speed tranny. I have a cold air intake, throttle body spacer, a jet mass air flow sensor and a cat back exhaust on it. I'm just curious about doing some of the advanced tuning on my truck to get the most out of it and hopefully not have any future problems. Just looking for some guidance as I haven't found any good videos online about advanced tuning on these i3 tuners

Uugghh....

Get rid of that throttle body spacer!! Doesn't do anything for ya.. gains you nothing.. those are an old-school carburetor trick and does nothing for newer fuel injected/direct-injected vehicles... it can also mess up the air flow and make things worse... so get rid of that spacer!!

Get rid of that aftermarket MAF sensor!! bad bad bad... Aftermarket MAF sensors do not report true, correct information to the ECM... aftermarket MAF sensor calibrations fool the ECM into thinking the engine is running leaner than it really is, so when trying to tune it and adjust the airflow/fueling correctly, it will never really be right/correct, because that aftermarket MAF sensor is not reporting true/accurate info to begin with... Plus, they usually cause idle and driveability issues... The stock GM MAF sensors are good for 600+ hp anyway, so there is no reason to change it... So put the stock GM MAF sensor back on!!

Then you will want to get a custom tune done for it...

Once you've gotten rid of that spacer and maf sensor, I can definitely get you hooked up with a custom tune... I've done a thousand of those over the years and do them weekly... and I adjust a lot more than what you can do with just the programmer itself...

With the custom tune, you'll gain even better/quicker throttle response & acceleration, stronger/harder pull, smoother & quicker power delivery throughout the rpm's, better tranny performance/shifting, improved towing performance, etc...  

I change a lot of things... a small sample of just some of the things are:  disable the DOD/AFM, disable engine torque management, adjust part-throttle fueling/timing, WOT fueling/timing, knock retard settings, throttle settings, tranny shifting settings (pressure/firmness, shift points, quickness), etc...

using the device to log will likely show it to be lean across the board due to the MAF.
Like Lew said, put a stock MAF back on it then log and tune from there, its the best option.
