Ok, Since my cam/rocker install, now my top end is really good, but it seems as if my lower range sucks worse then before the cam. I have alot of stumbling. ALOT. So I am going to replace my opti and my coil, also going to get LT1 edit and tune my CPU. After this if it still not fixed and running like she should be, what else could the problem be? I will also replace the opti to if need be. The car has 73K on it.

 

My recommendation would be to give your plugs, wires and coil some attention before doing the opti.

 

As usual,I agree with Shoebox.Do the easy stuff first.

 

that's what I was going to do. I am thinking about the future though. if fixing all the ignition stuff doesn't work, then what would the next thing to look at be?
