Tuners For 2018 Sierra "Hybrid" Truck?
beerpilot posted a topic in 2014-2018 Silverado & Sierra ModsI got a 2018 GMC Sierra with the eassist package. I never thought of this thing as a hybrid but GMC does classify it as such. One of the digits in the VIN specifies that distinction. I also recently picked up a Hypertech Max Energy 2 because I liked the options it provides for the AFM, specifically the speed at which it operates. The Hypertech didn't work, says the truck is not supported. A call to their tech support confirmed that the issue was the fact that the truck is a hybrid and they do not support that. So my question for the forum is, anyone know of a tuner that is supported on this "hybrid" pickup? From reading sites of other tuners it doesn't look like anyone makes this distinction of hybrid. I can return the Hypertech so a trial & error approach of purchasing another tuner and seeing if it would work is possible, but time consuming and annoying. Thanks in advance for help or suggestions.
Performance Tuner for 2016 5.3L
Kpv3484 posted a topic in 2014-2018 Silverado & Sierra ModsJust returned my DIablosport i2 as it would calibrate my speedo when changing to larger tires. Talked to Diablew who advised it is a known problem that hasn't been fixed... With that in mind, looking for input on the Bully Dog DT and Hypermax 2.0 Tuner. I know everyone on here says to go custom, but I just dropped $5K on my lift and wheels/tires so looking at something more affordable for now. Superchip and Edge don't support the 2016 Silverado 5.3L yet so those are out as well. Any help is appreciated! thanks
2017 GMC 6.2L AFM
Coleman71 posted a topic in 2014-2019 Engine, Driveline, & ExhaustI just bought a 2017 GMC SLT with the 6.2L and 8 Spd. It had 8700 miles on it. It will idle a little rough at idle momentarily. I only run premium gas, is that normal for the 6.2L? I've installed a Magnaflow 12909 muffler w/o flapper valve and an AFM Momentum CAI. Also, since I've had it, it has a tick that is heard when your standing next to it, or in a drive thru with the window down. Is that normal? After reading on here I'm worried about the afm lifters causing it. I plan on getting a Hypertec programmer so I can change the afm to 70mph and adjust the shifting so it's less clunky. I also will be installing an Elite Engineering EX-2 catch can kit. Will these additions help with the common afm issues? To make it more reliable in the long run? Anyone with experience or knowledge please educate me on this, thank you

Hypertech Max Energy 2.0 Tuner Suggestion
Bowtie619 posted a topic in 2014 - 2019 Silverado & SierraHey Guys, My tuner came in yesterday and I plan on tinkering with it this weekend. I thought it was odd that it didn't come with any manual and only a cd, I had to go with Hypertech because I live in CA and of course they are ridiculous about everything.. Anyways, I was hoping someone could drop some knowledge on me for the 2014 Silverado and how the tuner performed. If they like the performance or power tune better and what are the pros and cons of each? Benefits/Cons of turning off AFM? Did you feel a big change turning off V4? Also, My Speedo is off by about 6 mph when I get above 45+mph so I need to calibrate that as well. I have the stock tires so I'm not sure how or when it got out of calibration but it is. Any help on that front would also be appreciated. Those are the major changes I wanted to make. Any other suggestions would be greatly appreciated. Thanks!
Fuel Quality OKTIS-2
Dnt posted a topic in 2014-2018 Silverado & Sierra ModsHi guys. Was wondering if anyone had a easy way to keep a check on fuel octane levels? I saw this Russian made device OKTIS-2 http://www.ebay.com/itm/PORTABLE-FUEL-OCTANE-NUMBER-ANALYZER-TESTER-METER-OKTIS-2-NEW-/161886552305 looked like it would be useful for keeping an eye on octane levels and it is cheap (under 100 bones). looks like you just stick it in the tank and then pump some fuel through it, seems rather ingenious but not sure how accurate the thing would be? The reason I am looking is that I recently installed a canned tune from a hand held programmer for premium fuel 91 plus octane in my 16 Denali 6.2 I buy Shell 93 octane and the truck has run great for the first week after that premium fuel tune install but after I filled back up with Shell 93 octane last Thursday the next morning on the way to work I got the "reduced engine power" warning on my dash anytime the engine was over 3000rpm. I suspect that the fuel was BAD from my local Shell station but have no way to prove that...... I went back to stock tune friday afternoon and the issue is gone but now I do not want to use the premium tune without verifying that I am actually getting 91 octane or better fuel. Note: Gas line was busted in AL a couple of weeks back and Middle TN has suffered from spotty shortages of fuel (most notably premium fuel) I suspect that my local Shell had regular fuel loaded into their premium tank. (could have been a mistake) my plan is to run this tank all the way down to just a few gallons and then hopefully have a tester in hand and fill back up with REAL premium 91 plus octane fuel. Anyone got one or have something else that they use?
shakenbakeSierra posted a topic in 2014-2018 Silverado & Sierra ModsPutting a 6 inch lift and 35's on my truck. I notice it says you need the hypertech programmer to calibrate the tires for larger size. A buddy of mine Recently put at 7.5 inch kit with 325/65/20 on his truck without the programmer and every time he takes a corner, His traction control goes off and doesn't let him accelerate because it senses he's slipping. Does the programmer fix this as well? and does anyone know what size tires you can go up to without needing the programmer?
Hypertech Speedometer Calibrator
2011Chevy posted a topic in For Sale/WantedHypertech speedometer calibrator for GM trucks 2006 to current. This will recalibrate the computer settings for those who have larger than stock tires, it will also recalibrate the truck for any change in rear end gear ratio. Buyer is responsible for verifying compatibility with their vehicle. Price is $200 or best reasonable offer.
Bowtie619 posted a topic in Performance Engine TuningHey guys my speedo is off about 6mph when I get above 40mph (GPS has me going +6mph faster than speedo). I got my hypertech tuner for multiple reasons but one was that I was hoping to correct speedo calibration. I didn't do enough reading beforehand and it looks like the only way to fix this is through changing the tire size. The problem is I have the stock tires! So I figured what the heck I put in 31" for the size after measuring diameter and sure enough it didn't fix anything. My questions is... Can I increase tire size until my speedo is properly calibrated or would that throw something else off and create a potential problem? Any advice would be appreciated
So recently picked up a Hypertech Max energy (32000 model/ updated) from a friend for a 100 bucks, seems to work really well! noticed its got little more balls and the shift points really woke er up! Curious to see what everyone is running for settings off these things!
