Massive lose of power in Memphis...

The pcm biases the input from different sensors to tune be when its in open and closed loop. I'd guess that once it goes into closed loop whatever the computer is doing is less compatible with the change in input from its sensors resulting from the cam. Also bigger cam usually means the engine eats more fuel, closed loop is leaner than open loop. You're probably running lean as well. That's just me guess.

Get it custom tuned as has been said before. I went with Justin at BlackBear Preformance, he did a good job.

Yea I understand this but I mean wouldn't it still be in open loop at night when the engine is at operating temp? This idiot says the canadian can go play lipfrog with a fukn unicorn. I've installed this same or similar cam in the same trucks before with no problen on stock tune, throw in workin fine during the day and not at night is kinda weird. But anyways Thanks for all the input. I took my throttle body off in the parking lot earlier and cleaned it then run that idle relearn procedure and it actually idles on it's own again so far today, but i mean it idle'd fine for the first few days and then I had to start crankin the adjustment. All is well I guess until I'm on the side of the road.

i mean closed loop...

I would seriously get a tune...when I put my cam in it threw the same codes till I went and got it tuned the next day but I had that already set up to tune it and babied it home till I got it tuned....
You will never see the true power you can get unless you get it tuned...in my mind its throwing money away if you install a cam and dont get a tune.

Should probably get a tune. General consensus you see.

Just got back to Ga dropped it off at MTI Racing this morning, Vengeance would never call me back to make an appointment..

Yea I know it's just that stud broke and then I had to go on a job job = truck must move, it was 4th of july weekend and I didn't have a choice no one could get to it. Dropped it off at MTI today hope they can fix her up right.

sounds like you are getting the problems fixed...let us know how she runs after

Will do they've had it for 2 days now, will call tomorrow to see how it's going. If all is good and they do the tune I'm wondering what the gain will be. She had 226 whp and 267 wtq in 2007 when the Dynomax Dyno Challenge was here at Summit Racing. Got second place due to not a whole lot of people were there, the guy that beat me only had me by about ooooo 800 hp. I just wish I was in the position to go ahead with the 6l like i had planned on.
