I noticed a difference in the response and ease of acceleration with mine. My brother had a 99 bored .020 and fmf reed and pipes. He had the stock tube, and it was a BITCH to tune in after jetting. I have the same settup in my 98 but v-force reeds and the bottle, but it tunes in REALLY nice and I have complete control of the throttle. His was spuratice and the rpms took a while to come down, but Mine responds to the slightest input of the throttle. I don't think it help with horse power, but I would spend the money for the ease of tuning and good throttle control. Then again, it may just be the kick @#$ reeds too. I will say this, My shee with SMOKE his!!!! and his isn't much different then mine.
THere ya have it....lol
