Had the same issue with the TSP Stage 3
It's almost like I needed to jump 1 tooth on the timing to advance the cam 8 deg. Dot to Dot was not working... Why, I can't explain... I did a test on the VTT with the katech and if I retard my cam 8deg I have exactly the same behavior. Dip of torque above 3000 rpm then catch up at 4500-4800 rpm.
It's like my crank sprocket was off or something...
Anyway, the Katech makes even more peak HP and has stock idle and torque from idle... It's probably also the result of the whole package with Katech mastering valve train control...
