Go ahead and buy it and install it, but DO NOT do any WOT throttle runs until you can ensure there's enough fuel. You'll get the enjoyment of being able to merge with traffic on the interstate a little faster.

yes, during the tune flashing to the ecm and tcm, messages like that on the dash are normal, no worries there...

after tunes are installed and you turn the key off, remove it, put it back in and start up the vehicle, you should be fine and good to go - no messages...

Any complaints about the ...

+1 on all the replies. A very small percent of customers will take the time to give a positive feedback when a product purchased is working as advertised. As you said, it is what we consumers EXPECT!!! So why comment on it if we're already expecting it? Good on you for actually taking the time to ...

That has happened to me SEVERAL times. I'll tell you what else has happened twice now... My fob stopped working and I receieved a "service tire monitoring system" warning. The tire pressure indications would then be slashed out, not giving any readings.

I have a 2011 GMC Sierra. Luckily I am still ...

We need to see some WOT throttle logged.

There's a few adjustments you can make at WOT. One is adding fuel or taking it away. You'll need a wide band A/F gauge to read what your A/F ratio is so that you can add/take away fuel appropriately.

I can't recommend (and I don't think anyone else will) forcing air in an engine and not ensuring you have enough fuel. Trust me, there will be times you floor this thing and if you don't have enough fuel, you're going to ruin your engine. You're going to need the warm and fuzzy of knowing your ...

If you've got the ability to know what your A/F ratio is and have the ability to add fuel where you need to, then your engine won't blow.

I've got a wideband O2 sensor and the InTuner. I've got the wideband reading 12.8 through all the rpm's. I've read and asked a lot about what number to tune it ...

Excellent!!! Thanks Mike.

Okay!! Thanks for that info!!

I have high flow cats, should I still leave the COT on?

when setting up the TCM tune, what is the purpose of the "sport/tow" settings?
does that mean that I can basically set two transmission shift settings and switch to it by toggling on/off my tow switch?

I ...

Good day,

Here is some background information:

I have a 2011 GMC Sierra with LT headers, 3" exhaust, and a k&n intake. With all of this installed, I'm installing a wideband O2 sensor this weekend in order to better see what my A/F mixture is at since you claim that your preloaded tunes cannot ...

Good day all,

Just got my inTune and I've pretty much got it figured out. I was viewing a data log and did not see an O2 sensor reading. Is the inTune capable of retreiving this information? I have a wideband that I will be installing this weekend. I was just hoping to be able to plot my O2 voltage ...
