If you wanted to spend the money on quality crank fire CDI ignition, you could get some great torque numbers with CIS. Despite some of its limitations, CIS is a great platform even 30 years later.

You really can't do too much to the stock ignition system and that's a big problem when tuning for peak torque and HP. Leave it stock unless you get a quality system. And although Richard Clewett is tops in the Porsche world, the wasted spark system that Electromotive builds is nowhere as good as the stock CDI - even though you can set a timing curve. Given the choice, I would always opt for the stock CDI system over a wasted spark because of spark energy and the quality of Electromotive.

And yes, my 36 degrees is up to about 3000 rpm. At WOT, its closer to 18 degrees.
