I was going to say, you are already spending a crap ton of money and seem to be going in circles and still don't know what's on the car completely. If you were close, I would say take it to Brenspeed and let them fix it. They would put you up in their house while you were there as well for free. They could fix it, tune it, make it go zoom.

Assuming you aren't a terrorist or know drug dealer and can get into the US of course..lol

Lol funny, im clean. That could be an idea but im actually runing out of money with all this, not even sure i can afford another 500$ trip to a dyno, would be way more if i get to the states, i do remember getting told that the previous owner sent his pcm to roush in california to get tuned and the tune didnt work well. Im thinking two way my problem could have happen: engine was bad when i bought it, got worst with cams switch, or tuner ran a bad tune and heated engine

update: we finished installing everything back in places with the brand new rebuild heads, i was really excited, we started the car...guess what! pow POW pOw PoW in the exaust stil.. still thoses damn back fire in the exaust on the cold start, yes we do have fixed the weak compression in the two cylinders..but cant ****ing believe it, it still back firing, my uncle was discouraged like i was, he said it COULD be the tune since it started this way, so i went plugging the sct and loaded the previous tune I had when I bought the car, still back fire...
we're clueless, now were trying one last thing tommorow, putting back the HOT ROD cams in...this is where everything started, cams swap from hot rod back to the 4.6 oem cams...i know it sound ridicoulous thinking the cam could make the back fire, that what i got told, but still, I have aftermarket ported head...they might just not fit with the oem cams since they are bigger...I seriously put all my hope on that, otherwise, im screwed gotta remove engine again and start over from what...no more weak compression, how can this be never ending lmfao. wish me luck for tommorow result:/
