Ok here os a back story about it. Back when i bought the car had a haltech e6x. The previous owner took the stock leading ignition module, ran it to a msd 6a box and ran 2 blaster 2 coils. I have been using it like this since i got it. I switch to microtech because when i had the haltech i had tons of ignition break up. Now i don't but i do get a high rpm hesitation but i think is my turbo been small. I do plan switch to something different like a adaptrinic but I'm always questioning my ignition and in your opinion what you think about it? Should i get a stock coil setup or just keep running it like it is? Here's a pic of how it is And how normally burn, the light color ones are the trailing spark plus

 

thats strange the color difference between leading and trailing.. they usually look the same. It is as if the leadings are not getting enough power

anyway people seem to have better luck with the HKS twin power. iirc if you are running the msd box in waste spark, it is CDI only, and down from 6 at idle to only 2 strike above 3000 rpm, i forget what rpm it drops to 1, but you get the idea. it will work a lot better if running direct mode, which i am not sure your micrtech will do.

the twin fire is supposedly a combo of inductive and CDI, depending on rpm, which may cause better results. and it takes into account waste spark. the downside to CDI is very low duration at high RPM, which the twin power does not have this problem

 

If you're going run an Adaptronic, you can take advantage of the IGN-1A coils in direct fire. If you plan on just staying wasted spark, I'd probably just do a twin power.

 

Running too cold a trailing plug?

High RPM hesitation could be a lot of things. I've generally found FC coils to be very reliable and fine until one gets into the rich ratios at around the 400HP level.

 

I didnt know that you can get hks twin power for fc, i thought was just fd. I have a set of stock coils that i was planning to swap like i said i had this since i got the car and never did anything about it. I wish i can use ign1 coils but a new ecu is not on the budget right now. Ill look into getting a twin power swap all that. Thanks guys

Edit, no aaron, im actually running rx8 re9bt spark plugs both leading and trailing.
