TTDA question
There has been testing performed. Steve (the person who makes them) makes no claims of HP gains. What the TTDA does is keep you from loosing HP due to thermal soaking of the intake air prior to the boost phase. Increased intake air temperature causes the ECU to compensate by reducing the timing advance to preclude preignition.
The TTDA is a fine product. I have not read a single negative report.
Good luck.
