If you're really getting ignition break-up, you just need an ingition amp, just do a search for "ignition amplifier", "twin power", or "jacobs" and you should find a bunch of posts. Also, ironically, you asked about this a few months ago :

Though, I agree with classicauto, it seems wierd that a ignition miss would mess up your engine. I would think you generally blow an engine when you get ignition before you want to, not if you simply aren't getting inition.

Yes thats what the tuner said,as for EMS i use a Power Fc and today i ordered an HKS twin power amplifier, should i buy coils too?Do you think there is a chance a shortcut in the harness might be causing this ?and if so should nt there be some other symptom?

At last dyno the car made a bit more than 500 and iwas pretty huppy with it ,my only concern is to make them safe so that i can enjoy my car.Can you saggest any Multiple Spark Discharge unit,and why you find twin power so useless.

Knowing that i've spended more than 40k on upgrades I would say that funding is not a problem and anything less than the best part is not an option.For you to know ,i am really fed up with the so called tuners and mechanics over here so i've made arrangements to have Steve Kan flown over to tune my car on February.By then i need to have the car running perfectly, so could you please give me the tech details for this parts or point me to the seller!I know that i'm asking too much but since i like doing most things my self , wiring info would be much appreciated !

Here's where I'd start:
https://www.rx7club.com/rotary-drag-racing-167/msd6a-msd6al-2nd-gen-coils-spark-plugs-689629/
That is the minimum you'd want to upgrade at this point. This will allow an actual BOOST in charge voltage. The HKS system simply re-fires at the original voltage......boosting duration of the spark, but not its actual power/arc.
You can go further and add boxes for each coil, and run individual coils like an MSD blaster such as the SS - http://www.msdignition.com/coil_blaster_6_8207.htm

Back to the begining, are you getting ignition breakups? If so, try MSDs. I have the HKS TP, it does some work, but I guess you are aiming higher than I, so you must get something stronger.
But, are you getting ignition breakups?
