Just ordered a hypertech max energy for my 2014 silverado 5.3L. Anything I need to do or avoid or be aware of? Couldn't find much info here or anywhere. Thanks in advance.

Just absolutely make sure you go back to stock tune before you take it to a dealer. They will program over it and it's a PITA to fix.

I have two threads about it, look at engine section here and tuners in the other forum section

Thanks. I searched first before I made the thread but couldn't find anything. I'll try again.

I read your posts earlier but I didn't realize it. I didn't know if anybody else had any other input.

I have the 5.3L v8, 6" lift with big tires. I drove 350 miles highway last week and got 18 mpg, I thought that was pretty good considering my 2010 sierra SLT got 14 mpg with a 4" lift.

Think I can get better gas mileage with the hypertech max energy?

I haven't seen any in town savings Im still trying different things, I use to drive in M5 in town to stay out of the V4. Now with that removed I drive in drive my mileage is the same. Im running E85 so im using the max tune, I would be running 93 when I cant get E85. The change in the truck is very noticeable very responsive. I didn't realize how much I hated the V4 till it was gone. That kind of mileage with those tires is good.

Sorry if this is ignorant, but what's wrong with the V4?

Ruins any good exhaust, caused a slight vibration in my truck didn't see any improvement in town gas mileage.

Wormydog1724 · July 22, 2014

Interesting. I don't plan on putting exhaust on my truck and I haven't noticed any vibration. But I'll definitely know what to look for. Thanks for the help.

Didn't notice till the exhaust, these trucks seem to be very reactive to any change. Made me pause to doing any mods like a level, or 2-4 drop. Kinda watching here to see the average results from fellow mod nuts on here. I like how smooth these trucks are don't want to change that. Not to fond of the rake thou.

My truck just for reference.

[/quote Yes very nice.

I'm in the Oklahoma panhandle so having a lift is beneficial a lot of time in the winter. Although this is the biggest lift I've ever had, I can't say it's my favorite. A 4" is plenty and probably better all around. Hoping to maximize my gas mileage with the hypertech programmer.

Last trip I took I got 19 mpg at 79 mph on I45 between Dallas and Houston with 2k miles on the truck all stock. Getting ready for a trip next wk will see if there is a change.
