I almost thought about having this, or another, tune done. Now I remember why I didn't. I'm sure GM spent more time and money on developing these ECM/TCMs than a couple of guys with a laptop and a garage. I feel sorry for you knowing that you have to take a brand new vehicle back to the dealership to be fixed.

If it's just bad gas it will fix itself with good gas and a little driving time. Not a big deal. If the oil companies delivered what they promise I wouldn't have a problem at all. I'll still probably go for the 91 tune though, just to leave more room for lower-than-advertised octanes and/or ethanol blends.

If it's bad gas then it doesn't matter who programmed it. My Lincoln LS would knock all the time on various stations 91+. I'm not sure that discounting a sponsors work is necessary in this case....

The program did not cause any damage. I too believe it is the gas. I have done the different gas test, some knocked others did fine. When you run a vehicle with a custom tune you should ALWAYS run the best gas possible. As far as the "tuners" go. They are FAR from being just two guys in a garage playing with a laptop. They have been doing this for years on many different types of vehicles. I know for a fact there are a good number of member who are running this tune without ANY problems. If any problems were going to creep up it would have happened when the BETA tune was being tested. Could the extra horsepower and torque damage something? You never know. SOme parts inherently have weaknesses. A flaw in the manufacturing? possibly. Does it sound as thought this is something damaged? No, the code simply states there was knocking sensed. Please do not degrade or belittle a site sponsor. They are here at their own free will. They help the site exsist.

If anyone has a question on the reliablility of the product a sponsor or anyone on here is selling, please PM them.


Thank you

I can't think of any site sponsors who have been more informative or helpful than Chris (though the Westers guys were nice too). I'm convinced that it's not his product, and I would put my money on it being the gas. Some people had concerns with the knocking from the Westers tune that were solved by switching gas stations.

Besides the CEL coming on how does the tune feel? AWD or 2WD?

Nice! My truck is AWD. The 1-2 light-throttle shift is much better than the stock "slip-bang", though not exactly how I'd like it (kicks too much IMO). Overall driving is better. WOT pulls harder. Fuel mileage TBD yet. Other than the 1-2 shift I'm very satisfied! Now we'll just see if this low-octane problem clears up. If it doesn't I'll get a 91 tune and have them soften the 1-2 shift to feel more like the 2-3 shift.
