So had my truck towed to my tuner he tried to program the ECM and could not do it. He said the tuner erased the ECM and i have to get another ECM. On with the questions first off how does this happen? and second i found some ECM's on rockauto and wondered if they are the same as the stock ECM in all lightning and what the difference in price is heres the link.

I understand that it is one of the only programmers that can be tailored to what you have in your truck. I will say that is a great virtue it has over most others. But I bought the edge evo before I knew about the gryphon, before I even became a member on this site. I do not see any major benifiets to swithing over. I am currently very happy with the set up I have now on my truck. ( CAI, EDGE EVO, FLOWMASTER 40D SISO)
I did some research through both companies, I called edge and asked if they provided or had guidence when it came to custom tunes. Obviously they said no and sent me to powerhungry performance. So, I called them and asked what they had to offer. The gentleman I spoke to said that if I am having no problems with my truck, there most likely won't be, and it would be a waste of my money to switch over. This is a salesman at POWERHUNGRY PERFORMANCE! I thanked him for his honesty. I also informed him that I had a CAI on my truck. He said great... what's the problem. So did some more research...
I found that the horsepower gained from a CAI IS FROM the lean conditions. It allows for more air to get into the combustion chamber, to allow more efficient combustion. Meaning you do not need as much fuel to create the same amount of horsepower (but our 5.4 engine does compensate with more fuel, making extra horsepower). The MAF is more than capable of handling the extra air into the truck also, it good for about 450 HP (and the oil from the filter only clogs the MAF is someone is stupid and over oils there filter). And if you try and compensate for the CAI with a custom tune, you are basically canceling any gains in HP out. Now all of the sudden there is a 300 dollar cosmetic part underneath your truck. Whats funny about the prized Gotts mod is it does the same exact thing, only it is cheaper. I do not believe it is as efficient as the tested and proven K&N CAI. Hell, the military uses K&N technology on its UAV's. Trust me on that one.
So, what I am really asking is, has someone done more research? Am I missing something? I love my truck, and I love the engine, and I do not want it to break. But i do not see the point in switching to Gryphon. And people keep preaching it everytime some one mentions CAI. Also, am I wrong about the CAI? I have had the CAI for about 12,000 miles. I have had the edge evo for about half that. So far I have had no problems. I have only gained a more pleasurable driving experience. I just installed a flowmaster muffler this weekend. I love it. But like I said, I have had no issues with my truck. So I am seeing this custom tune hype as exactly what it is... hype.
