Works, I think
Truck:2015 GMC Sierra Denali 1500 (6.2-8 speed)
Turned off AFM and speed limiter, currently running 93 octane tune (stiff shift points). Not sure I notice a considerable amount of HP or torque gain(Would need dyno for that), but the idle is smoother and also, I’m not sure if the shift points are “stiffer.” Just turning off the AFM makes the truck run better though, no more getting caught between gears and cylinders👍🏼
Time will tell if it actually increases MPGs. I saved about $200 buying refurbished model. Seems to be brand new, no defects that I’ve noticed.
Overall, seems like it was worth it...so far.
I say, buy it.Read full review

2004 Chevy Suburban Install
I really can't say it did much for my 5.3 for power gains. The throttle response is a little snappier and with the 87 octane tune it gained about 1.5 MPG so it wasn't a total loss. Just for reference my Suburban had a K&N air cleaner, airaid intake tube, 40 series Flowmaster before the I3 install. If you can get the refurb for $188 I recommend it however for retail of $342 I would pass on the install.Read full review

Very good, but not great.
Bought this for my 2015 Silverado to get a little better shifting and to disable AFM (or DOD) after getting a new Magnaflow and dual pipes. The programmer itself is very easy to use, basically plug and play. The only reason it's not 5 stars is the documentation that comes with it is pretty weak and does not fully explain what the canned tunes do or what all the sub-settings you can change do. For that you need to search their forums or hop on Reddit.
Once you figure out what everything does, it's easy to make all kinds of changes. I haven't delved into all that it can do as I have not really made any major modifications to my 5.3l engine.Read full review

I3 platinum
Installed 87 octane tune and get almost 4.5 mpg better. Changed tire size, but need to manually tweak. Great product for 04 Silverado 2500.

Best upgrade I’ve done to my truck yet.
I haven’t dyno’d my Silverado but by the seat of my pants test this thing made a huge difference. I haven’t dug in to all the settings but just applying the 87 octane tune and turning off the 4 cylinder mode totally unleashed my motor. I purchased a refurbished model and had no problems. Highly recommend!!Read full review

Good product, touchscreen is a bit tricky.
For a refurbished product it works great. The only complaint that I have about this product is the touchscreen and using the menus. When trying to navigate the menus and use the touch screen it can be a little difficult to get your prompts to work 100%.Read full review

Received the DiabloSport 8245 Intune I3 Platinum and on opening the shipping package you wouldn't no it was REFURBISHED just looking at it. First tune to 91 octane fuel turned off the V4 Mode and made my 2007 Silverado run like a different truck, My only complaint and why i only gave it 4 stars is because you can't edit the saved stock tune with any open source tuning software, its in a proprietary format and you would need Diablos editing software for that.Read full review

Thumbs up
Paired it with my 2011 Sierra Z71. Done everything it said it would. Currently running the Diablo 91/93 octane tune, no Tm, Firm shift tune, disabled afm/dod, raised speed and rev limiter, and left everything else alone. The trans tune fixes the bucking, lurching, and half wit confused 6 speed trans issues making it much more driveable. For the discount of the refurbished unit compared to a new one, its a no brainer! I3 looked and performed like new.Read full review

Works great, new tunes for 2018 GM!
2018 Silverado 4x4 After updating, plug in to vehicle, then update again(a little annoying). Then you are ready to program. Programming requires a little previous knowledge or go watch YouTube before attempting. I adjusted my speedometer based on new tire size and disabled the active fuel management(DOD). I also used the 87 tune. Didn’t gain any mpg, but truck feels powerful now like a truck should. No more delayed throttle response. I did not program the TCM, but it no longer “searches” for gear, I assume this was due to the active fuel management. I give it 5 stars because it accomplished everything I needed it for.Read full review

Good programmer but not excellent.
It does a nice job tuning the engine, but forgets about the transmission. A slight bump in line pressure and shift timing is nothing spectacular. They need to adjust shift points and torque converter lockup too. Maybe some day they will hire a programmer familiar with programming Chevy trucks.Read full review
