2014 Silverado Crew Cab on 33's - 5.3L

Hello,

This is my first time posting in the DiabloSport forums, as I just purchased an Intune I3 Platinum Programmer.

I am looking for some decisive direction as well as suggestions on the best parameters for tuning my truck with the I3 Platinum.

Specs of Truck:

2014 Silverado Z71 LTZ 2WD Crew Cab
Rough Country leveling kit installed
33" x 12.5" x 22" Nitto Terra Grappler G2 A/T tires
5.3L Ecotec flex engine
K & N Cold Air Intake installed
Gentle 46k miles
I RUN 93 OCTANE IN THIS TRUCK

Being a 2 wheel drive (It Does have the Z71 package, Rancho shocks, etc...) Obviously it raked in the front.
First thing I did was put the K&N CAI on and it was like a rocket in Manual 5 gear mode, when I shifted through the gears myself.

After leveling kit and 33's with aggressive tread, it was complete garbage. No power, confused shift points, almost like missing. Just a hot mess.

So I bought the Intune I3 first, rather than switching to a 4.10 gear (which I may do later).

Already turned off AFM and that was immediately effective. Also, 15% throttle boost.

Can anyone suggest the best parameters to make this bad boy get up and GO!!??

I would like to know if there is a good idea on what ECM and TCM adjustments should be made to not only get that stock power back on 33's. But also get good fuel economy.

The standard Diablo Flex, Jammer and 91 tunes don't seem to help a whole lot. Still bogs down and takes forever to get through 1st and 2nd gear.

Please help!!! Here's how she looks now....

All of the talk about lewtunes is what got me to buy a Diablosport tuner in the 1st place. I have yet to get my custom tune but my understanding is it is night and day. Here is a link to webpage
