TruXP XTune+ Tuner - Surprisingly functional for me

Rob Okray · February 24, 2018

For the price this seems like a screaming deal. Its on the buy list. First I need to uncork what is already there with a fresh air intake and less restrictive exhaust.

I got the tune installed last night and went for a drive and I can tell the difference for sure. I installed the 91 octane tune, and disabled AFM/DOD. Much better throttle response and seems quicker 0-60, seat of the pants feel. I like it.

Thanks for the update above too!

Try Pearl. Smoother than GG and half the price.

In the gear ratio section of the stock tune select are the ratios picked from a table or by some incremental push of buttons. I need to know if the 3.90 gear is an option.

I’ll check and report back

I chatted with a Autoanything. It won't work with the 4.3 so it matters not, but thanks.

So will this work on a 2017? I went on the website and when I put the year make and model in it’s telling me it’s not compatible.

It worked on mine, 2017 Silverado 5.3 Z71

Absolutely. I took pictures of and then reset all the fuel stats. I don’t drive every day but I’ll post back when I have some good data. All “city” driving.

Yeah I was reading your posts. So should I call and order it and tell them to send me the update at the same time?

You might be able to get the "unlock update" prior to receiving the tuner but I'm not sure. Powerteq is the company that sends the "unlock update". Maybe if you call them after your purchase and send them the receipt email? It's an overnight wait for the update, maybe sooner if you call Powerteq like I did.

So this is the 25 mile average after around 200 miles. 1st pic is before 93 performance tune, 2nd is after the tune. and I've been fairly heavy footed since the tune. It's basically the same for all the fuel distances (25 & 50).

I got my Xtuner today for my 2018 Silverado Z71 and at first I was a bit disappointed in it. Then I watched WaterFowler's video and learned how to play with it. I started out with the Stock with options and shut off the AFM. That was reason number 1 for getting it, but I was hoping for a small boost from it too. I took it for a ride and it worked but for some reason the truck felt different. Almost kind of sluggish. And it seemed like the shift points stretched out some. It also looked like in the book if you wanted power increases you had to change fuel octanes to get any boost. Watching the video and from some of the posts was where I seen you could tweak an already canned program. I went with the 87 Octane program and found where the throttle boost was. I boosted 10% to start. WOW. To much LOL. Making a right turn was pretty hard to do without the back wheel wanting to chirp. I back down to 8% and I'm happy there. Even that sets you back from a stop while hardly getting into the throttle. I LOVE it. My only issue is almost all the programming available says they are not designed for towing? I do tow a boat and tow a trailer with yard equipment or building materials on it every so often. Do they mean that I can't use "Tow Mode" anymore or are they really saying I have to remove the tune to pull anything behind me at all? I don't use Tow Mode anyway so that's no biggie, but to not be able to use the extra power for towing at all kinda defeats some of the purpose of the tuners benefits.
