I have one in my RR now and I rode my bike the whole week to work. Well I had to fill up 3 times. that will last till sunday. My friend who rides a gsxr 750 thats all beat up only filled up once so far this week. He uses 87 I run 91. We both have pipes on the bikes. Would it make a huge difference in gas consumption if I removed the PCIII? And if I did remove the PCIII would I have to do anything other than just disconnect it ?
