We bolted our new carbon fiber intake to a completely stock CT4-V Blackwing, and instantly gained 30 to 50 peak whp. Even more impressive is the 70 plus whp gains we saw near redline! These performance improvements take place with no other changes, and no tuning required. Idle, drivability and fuel economy will all remain the same as stock, as long as you stay out of the boost. There are no DTCs or Check Engine light issues. With Green performance air filters, Brisk spark plugs, JB4 tuning module and a custom tune on our in-house dynamometer, we were able to get total gains of more than 100 whp!
