Collaboration with VF Tuner with development and real world testing of the Toyota/Lexus map switching using factory cruise control buttons. This is an example on my personal 2015 RCF. This feature will be rolled out to all Gen2 2URGSE models.

Dyno tested the RCF with the new GFC_Exhaust_Factory titanium midpipe with 3D printed titanium Z-pipe. The car is slightly more efficient in making peak power and torque while being much more tame and quiet compared to the non-resonated H-pipe.

📈 There was an increase of midrange torque by 9FTLB at 4600.

There is also more midrange power of 10WHP at 5500RPM. The top end power also increases between 6200-6800RPM compared to the previous H-pipe set up.

This Dynojet is a low reading dyno since it does not have load control. No other 2URGSE car that has been on this dyno is able to achieve greater than 450WHP in 4th gear other than my own RCF.
