I understand your doubts about temperature vs power (worth the cost/effort I'm sure). Just keep in mind that temperature controls under the hood have more to do with power consistency and power band rather than peak power. Besides, I never mentioned anything about an increase in power.

The peak power and torque are most likely unchanged, but what was immediately notable was turbo spool and consistency of power delivery. I am in the process of getting data on temperatures and pressure with and without the system. I met with an engineer this morning and was discussing theory and acquiring a data acquisition system for this project.
