I have the Delteq on my current setup. I am currently still contemplating whether or not to use it on the Z when I swap my stuff over to this car. That car has a Crane ignition box on it and I was seriously thinking about just going back to an opti setup. Have I had problems with the Delteq? No. There are a few things I don't like about the Delteq such as not having an ignition retard and no rev limiter. I will also say that after I installed the Delteq, I had to get another opti anyway so I shelled out the dough for ignition components. The reason I had bought the Delteq is cuz my coil died. I can't really remember all the details but we thought my cap and rotor had took a dump. Turned out later to be the coil. I'm kinda leaning back towards the traditional setup cuz of the features like retard and rev limiter.

I run the DELTEQ kit on my car with the stock opti at 126k on the clock... My car was cutting out when it was warm and would stutter when you gave it gas... I put the delteq kit on and havent had a problem since... Will prolly have some problems before too long just cause I am saying I havent had any problems... And I also have MSD coils

Delteq or LTCC both are fine so I hear, the new MSD opti (too new, have heard mixed issues with overheating due to the billet design, etc). Personally right now I'd put a new GM opti against all three, the Delteq, LTCC or new MSD and still do just as good (if not better). I say this based on results from various posts and the searching I did myself prior purchasing the LTCC, which I wanted for nitrous control down the road and liked the individual coils idea.
Some have had issues with Delteq, LTCC & MSDs new setup, others are doing fine but I'd recommend searching here and also camaroz28.com to fulfill you're inquiry.

My setup is doing just fine. MSD DIS4, DELTEQ, Dyna-Spark GEN III, (4) MSD red coils and more 
I agree, some people have all kinds of problems and others don't have any problems. Its real hit & miss with these setups for some reason ?

I took the unit off today and found that the rotor had been rubbing against the housing apparently causing the thing to give the error code. It appears on the MSD unit that the rotor either sits too low in the housing, or somehow the shaft in the housing rides deeper and goes off balance as the unit gets more used.
The MSD had only 4000 miles on it. It's the first year for the MSD Optispark, and clearly there are bugs that have to be worked out. There has also been high demand for the unit so production problems may be a factor. I would note that it is not the MSD cap that is the problem so you would be okay buying one of them. Just the base distributor appears to have a problem in my case. There is someone else who posted this problem also so I'm not alone.
I will post to let people know how MSD handles my warranty repair.
