So wait you took a chevy chevelle to a ford mechanic had him put in a gm engine and your having problems? I suggest you take it to someone that actually works on lsx engines. Check out our sponsers listed to the right I'm sure one of them could help you.

^^^How about some constructive criticism
Did you use a factory harness or something like a painless system?
Id start checking all of the connections. It does have knock sensors in the valley cover under the intake right? There should be a short harness coming out the back of the motor under the intake. Also how many o2 sensors are you using? If you are only using teh front ones the rears need to be turned off in the computer otherwise it will log a code.
If its bogging and backfiring something is probably wrong in the tune or the sensor wiring. You should really take it somewhere that knows the system, CMS could help you out for sure.
