We just wrapped up tuning here at Diablo, and are excited to have the first installation and tuning numbers to release for the 2009+ Challenger R/T with the Techco twin-screw supercharger! Bone stock the car put down 334 rwhp. Now with the Techco supercharger (plus the MBRP catback and 85mm throttle body), I am putting down 467 rwhp! That's a 133 rwhp gain over stock in all. The RWTQ went from 352 bone stock, to 471 with the current Techco set-up. Special thanks to Carlos at Techco and Johan at Diablo!! Here is the thread with all the pics and videos from the installation at our shop: http://www.srtconnection.com/forums/showthread.php?t=12965
