Justin brought his VB WRX by for some more goodies!
This go around included a Cobb Flex-fuel kit, Motul oil change. To go with his Grimspeed intercooler, and Perrin intake.
The results were 349whp/389wtq on E50 and 291whp/312 on 91 octane. Calibrated by BWTuning via Cobb AP.
Ethanol wakes these cars up tremendously!
