What did I do wrong
What did I do wrong Ok here goes, I swapped out my zz-409 cam for a stock cam drivability and fuel reasons. Upon turning it on the car idled fine then when i tried to give it gas it starts to backfire really loud. could it be that i adjusted the RR wrong. i took the pcm to get flased back to stock setting so i dont think that would be the problem. help please
it could be checking a ton of diagnostics on the car, same thing happens with a new battery, did you drive the car at all since this happened, it could also be that the reflash didnt go well.

no i have not driven the car i dont want to risk it with all that backfire. so u say it could be to tight i went with 3/4 of a turn since i put back in all the stock components exept springs.

the thing is that it back fires really loud and as soon as i give it gas is when it does it. i doubt the RR are to tight but i could be wrong. At this point i will try anything 
Well you are on the right track since you are willing to admit you may be at fault. Seen a lot of guys fight admitting that possibility and waste a lot of time and money as a result.
The mechanical timing concern is one I share, but easier to check would be the rocker adjustment. How did you find zero lash?

as far as the wires never even took of the plugs and wires so id cross that one out. If in fact i did mess up with the timing dots how would i fix that or check more acurate

^^From what I know you'd have to pull timing cover to check timing. This is just a thought but if you indeed had dots lines correctly you might have had #6 at TDC instead of #1. Someone let me know if this correct or possible.
Surly you pulled the wires off the opti end right? Check to make sure they are correct, seen guys spend a lot of money trying to fix what turned out to be mixed up plug wires. Every last one of us has made a silly mistake like that.
Like the person above me said, if your pulled the opti off, I'm sure you pulled the plugs wires off the opti
