You likely wouldn't need to go through any of this headache. Your DME should (I'm not certain on this but theres a high probability) be able to natively control some generations of factory 8HP TCUs. However, that limits you to the stock TCUs feature set which may be detrimental in drag racing (no transbrake).
Is the DCT becoming a limitation for building boost at launch or something?
