I recently installed the unortadox udp. No noticeable gains so far, maybe its like the y pipe the car has to learn it anyone else notice a differance.

The car doesn't have to learn it. Small gains are hard to measure on the butt dyno.

well i got both mine installed on the same day as my y-pipe, 4 hours apart and i noticed my revs are a lil faster. then when the y pipe was put in i felt the power immediately increase, esp in 2nd gear. car seems to accelerate alot faster then before. i also added some sea foam to the gas and crank case, cleaned out TB and had an oil change. car feels great!!!

i think that with all other bolt ons, the UDP just helps with the addition of all other bolt ons, just my theory lol
