I put a slip on, on my 06 and changed the air filter and it was running way lean so I went with the Cobra FI2000r and it cleaned it right up, no popping or anything on high speed deccelaration like it seemed to do before. Plus the FI2000R is plug and go and it has only 3 pots to dial in to your liking and is very simple to install, It took me about 20-30 mins. to put in. ( No laptop needed)
