I have to agree with BlackZL1
The JDP VMAX works as advertised, I have the Roto-Fab CAI installed also. No 5% pulley yet, but it's coming. What I noticed after the install of the T/B, besides the cleaner /quicker throttle response. Was how the car accelerated when in 4 & 5 gear running down the interstate. It was a noticeable improvement in how the car accelerated
