HP Tuner

[Dan Martin]

Anyone running an HP Tuner on their N/A, Catback 5.3 K2XX? If so where did you get it from?

Yeah, I've been using HP Tuners since 2012.

 

I bought it straight from HP Tuners themselves, why hassle with summit racing or any other re-seller when buying from the actually company is that easy. You'll need the tuning device plus however many credits your vehicle takes to license.

 

Just know that HP Tuners does not come with tunes or anything, the user is the person making all the changes so you will need to understand how things work in the GM world of calibration.

Okay, I’m coming from the Cummins world, where you could purchase pre-tuned EFI Live downloaders. That’s why I asked that way.

How much of a bear is it to tune? I am computer savvy, but I don’t wanna screw things up

I'll be honest here, if you've never done anything like this before it will not be easy. The 2014+ trucks run basically the most advanced calibrations that are out there for GM vehicles aside from the T1 trucks that just came out.

 

There are courses and books/video's you can buy to better prep yourself. Greg Banish at Calibrated Success offers books and video's. There is also The Tuning School and many youtube video's to shine some light on what you will be dealing with.

 

I learned on the computers that came out in the late 90's through the early 2000's when I first started tuning in 2012, so everything I learned on those computers carried over into the newer 2007+ computers while also being introduced to new things in those computers. Then as time went on they progressed and once 2014 came, things got more complicated but most of the same basics still applied.

 

 

There are other options out there if you don't want to do it yourself. Like a dyno tune from a shops or finding a local person that does tunes. I've never been a fan of handheld tuners so I don't all of those options.

Kinda what I thought. That’s more or less what I was looking for. If I purchased the tuner and the licenses, if anyone was selling tunes or if I’d have to find someone somewhat local to me in MD.

What mods have you done to your truck so far?

Right now it’s CAI and exhaust. I will eventually go the route of forced induction, but I need something to tide me over and I was looking over my options.

Cam stated right, hp tuners is pretty invasive when it comes to control. I have been using it since 2015. I acquired most of my learning from videos and the hp tuners forum. In my opinion it is a great skill to learn if your planning on tuning or having most of your vehicles past present or future tuned. It took me a good year to learn enough to feel confident in tuning. A lot was through trial and error but helped instill the concept. I also believe it helps one understand how many of the vehicles systems work.

There are companies that will send programmed tunes for Hptuners and have you do some data logging to fine tune it.

i have the old HPtuners module,  I wish i got the pro version, as the number 1  performance tune upgrade you want to do is Improve PE tables, this is where the most bang for the buck power is hidden, close to 50hp is left on the table under PE. this is dialed down due to emmission regs by GM, 2500 truck have it turned off completly on some model years., thus why you need the live wideband O2 graphing.  I wouldn't touch the timing, until you got some seat time, I would recommend tuning your transmission first.

That’s another reason I was looking into them, because I wanted to find a product that could tune the transmission as well. I’m gathering that I should get the book and do a lot of studying first.

yes get the Greg Banish books, then watch sloppy mechanics videos and Goat rope garage you tube videos,  then you can buy the GM trans tuning books for HPtuners .  also you want to purchase the chinese  VCX Nano  device to read and clear transmission learn functions, and tb relearn, and body control computer for diagnosis..  if your really anal the factory repair manuals cant hurt. either on CD or paperback
