Last track day was a waste because my car was down on power and breaking up at high rpm. It starts fine, idles normally, and drives well under part throttle. Under full throttle at higher revs it starts to miss, and gets progressively worse as temps increase.

Does anyone know the specs for the coils? No specs are listed in the manuals. I searched and found that the question has been asked on this site but not answered.

 

Do you have engine management, or is this a stock ECU?

 

EMS V2

Found this interesting... from the Denso website (http://www.densoaftermarket.com/faq.php)

"I found alleged DENSO flow rates, voltage output and other technical data on other independent web sites. It says that the data is correct and direct from DENSO. Can I trust it?
No. Absolutely not. Since DENSO does not publish technical data. Whatever you may have found is merely speculative guess work from tuners and enthusiasts."
