Instant results after the installation of my 63 Series. Noticing roughly a 2 mpg increase and a much better throttle response. Installation was very simple. Set up everything I could inside, went out to my truck and finished the installation, took no more than 45 minutes. By the way, it sounds great paired up with my Magna Flow exhaust!
Most significant thing you can do for performance for the $$$$
1 hour and 1 beer later had it installed. Pay close to the instructions about where the grounding wire goes but other than that is was the most simple thing I can do to my vehicle to improve performance. Kinda sound like and responds like my Dodge Charger Pursuit Police Vehicle...it hops to when given the gas!
