Yes the Sprint Booster SBCY00036 from Jegs High Performance. It WAS on sale for 20% off (now over). I can not believe the difference! It has 3 settings (normal, sport, race). In the sport and and race settings there are 9 degrees. SO......... set out in "race 9" and ......................HOLY ****!!!!!! The SRT came alive. Over priced? Not in my opinion. So drove in normal (not for long). Amazing.... for $180.00 and plug and play. Don't knock it until you try it. Way beyond my expectations.
