A 70 mm TB is plenty (read more here), a 75 won't hurt performance but it can make low rpm cruising (1000 to 1200 rpm which is arguably too low anyway) a bit twitchy as compared to the stock 65 mm TB.[/align][/align]I have the Pro Products 70 mm TB and their plenum (same as TrickFlow) and am quite pleased with them...[/align][/align][/align][/align]
