I recently installed a flowmaster 40 series muffler and PROFAB cold air intake on my truck hoping to gain some kind of noticeable performance increase. While the truck sounds great and still runs very strong it seems to have gotten sluggish from a dead stop. It feels like the throttle is not responding as quick as it was prior to the modifications. Can someone please help me out with this? Very frustrating... Any guidance would be greatly appreciated.
